It is shown, in the future, when the magnitude of the deceleration parameter becomes, -1, that the universe attains a state where the volumetric strain rate becomes a minimum. It is argued that, for this reason, the universe then remains in this state indefinitely.The trajectory of the deceleration parameter of the universe from the present time into the indefinite future, as shown in the diagram in the body of the work, is then simply an exponential curve followed by a horizontal straight line. 20 pp. Englisch.

Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Academic Paper from the year 2022 in the subject Mathematics - Analysis, grade: 2.00, , language: English, abstract: Given their importance as the building blocks of all of the integers, the prime numbers, their number and dispositionwithin the integers have been studied for millennia. In 1859 Bernhard Riemann published a short paper (which only extended to six manuscript pages) concerned with an investigation of the number of prime numbers less than any given number. The outcome of the work revolutionised number theory and in the years following has resulted in almost what could be termed an industry in a particular aspect of his work, now called the Riemann Hypothesis. Riemann showed that all the zero values of the zeta function in the positive part of the complex plane should lie in a region between x = 0 and x = 1, and, in particular, conjectured that they all should lie on the line of symmetry x = ¿. This conjecture, which is the basis of many other conjectures in Number Theory is considered by many mathematicians to be the currently greatest unsolved problem in Mathematics¿so much so that the Clay Mathematical Institute of Boston, Mass. has offered one million dollars to anyone who can produce a solution. No attempt is made here to verify the hypothesis, for its validity is not required. A procedure is developed here, by means of which, the zeros of Riemann's zeta function in the so-called Critical Strip of the complex plane may be assigned values of the prime number counting function. The procedure is novel and uses the concept of a Dirichlet line in the complex plane and a quantity called a nearodd (both of which are defined in the text). The process may be rendered self-contained, in the sense that, when it is associated with Gram's series the only input required is the magnitude of the imaginary part of the function s = x + iy which will locate a Riemann zero on the Critical Line; vast numbers of zeros may be accessed in [2]. Further, it is shown that the Riemann conjecture is irrelevant in the assigning of any particular value of the prime number counting function to the corresponding Riemann zero. It is suggested, pace Wiles, who obtained a proof of Fermat's Last Theorem as a by-product of his verification of the Taniyama-Shimura conjecture, that, in the light of Godel's incompleteness theorems, Riemann's hypothesis may be undecidable. 20 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Essay from the year 2019 in the subject Physics - Theoretical Physics, grade: 2.00, , language: English, abstract: It is posited that the frequency of electromagnetic radiation may be quantised and two methods are derived which permit the calculation of the magnitude, delta, of the quantisation.The work does not establish the existence of frequency quantisation and the two methods derived may be described by the oxymoron, systematically arbitrary.Both methods rely upon the Fidler diagram.The first method employs the superposition of a fractal path on the diagram and gives, delta = (V)/(sqrt 2)^(n-1), where n is a disposable odd integer, and (V) is the Planck circular frequency. The second method involves the tiling of the diagram by a succession of self-similar tiles which are progressively-reducing versions of the diagram itself. In this case, delta = (V)/ (sqrt 2)^(2(n-1)), where n is any integer.Erratum: The relevant Planck quantities on p16 should read:Planck length, (L) = 4.05134\*10^-35 m.Planck circular frequency, (V) = 7.399825\*10^42 Hz.Planck spectroscopic wave number, (Z) = 2.468316\*10^34 m^-1.Planck specific energy, (S) = 12.1026\*10^43 J/m.Planck specific energy intensity, (I) = 2.987308\*10^78 J/m^2.Planck specific energy density, (D) = 7.373629\*10^112 J/m^3.The work also shows that the Fidler diagram is the two-dimensional projection of a three-dimensional surface. 20 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Academic Paper from the year 2021 in the subject Mathematics - Analysis, grade: 2.00, , language: English, abstract: It is demonstrated in this work that we may construct an infinite number of strips in the complex plane having the same 'dimensions as the Critical Strip and which are devoid of Riemann zeros except on the line of symmetry. It is shown that the number of zeros on each line is infinite, indeed, there is a Riemann zero at infinity.It is posited that a form of the Riemann conjecture is verified in each strip. It is shown that each integer in the infinite set of the integers has an associated Riemann zero and that the imaginary parts of the complex number at which the zeros are located are proportional to the 'local' asymptote to the prime counting function. A connection between the prime counting function and the zeta function is established. A limited distribution of the Riemann zeros corresponding to their respective prime numbers is constructed and it is seen that, at least over this range, the two are correlated, albeit non-linearly.It is demonstrated that the imaginary part of the complex number locating a Riemann zero may, for any integer that can be articulated, be obtained by a few keystrokes of a hand calculator. 16 pp. Englisch.

Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Academic Paper from the year 2022 in the subject Mathematics - Analysis, grade: 2.0, , language: English, abstract: This paper devises a hybrid function, denoted by H_a, (where a, is a real constant), which consists of the linear combination of a novel form of the Riemann zeta function and the abscissa of any point in the complex plane. These functions comprise an infinite set, for the value and algebraic sign of the constant are unconstrained. Amongst these functions, H_(1¿2) is unique, in that, the magnitude of its value at the intersection of any Dirichlet line [1] with Riemann¿s Critical Line [2] is shown to be absolutely zero and that there are no other zeros of this function anywhere else in the Critical Strip. There may be other zeros of this function elsewhere in the complex plane, but this paper argues that this can never be proved; this is a feature of any other of the H_a whose zeros can be posited to exist at the intersection of a vertical line passing through any abscissa of choice with a Dirichlet line but, can never be shown to be exactly zero, since this would require that the Dirichlet alternating eta series associated with the real part of these H_a be summed to infinity. It follows from the above that, for the function, H_(1¿2) Riemann¿s hypothesis is verified. 24 pp. Englisch.

The terminology appropriate to a staircase is used to describe the parts of the distribution amongst the integers. Strings of limited extent of consecutive numbers which may contain prime numbers are generated from an iterative equation which contains Gauss' prime number counting function. In honour of Gauss we call these strings of numbers, Gauss strings. , and they are used in the construction of the staircase. Further, we show that the prime number counting function may be represented in number space by an infinite set of connected trapezia, the individual areas of which are numerically equal to the gap between the primes that are situated on two of the borders of any given trapezium. 20 pp. Englisch.

Strings of consecutive numbers are extracted from the matrix, and it is seen that the only places within the whole of the range of the counting numbers where prime numbers can exist is at the positions of the second and penultimate numbers within a stringBy means of the function of N, all of the odd numbers may be generated and examined for primality. 24 pp. Englisch.

A single equation is derived which, in a sense bifurcates into two slightly different forms upon the making of one term explicit.We can even extend the simplest definition of a prime number expressed in [5] by the addition of the phrase ¿ and can only possibly be found in the range of the counting numbers at positions on either side of any number which is divisible by 6 ¿. 16 pp. Englisch.

It is shown that there are a new set of numbers given by F = (M + 2)/3 where M is a Mersenne number. it is found that when M is prime then F is prime. however, it is also found that prime numbers may be generated when M is composite and the index of the Mersenne number is prime, but this is not invariably the case.An accelerated method of trial division is derived and from which we construct one row matrices which we have called, templates. These are found to be of great utility in determining factors of numbers, and their 'extent' is equal to the number of digits in a number of interest. The template may be easily extended by a simple process explained in the text. Extension of a template by one unit increases that range of numbers which may be examined by an order of magnitude. 20 pp. Englisch.

In this work it is shown that the series is infinite and indeed, has the sum 0.5. The methods of solution are novel and employ accepted mathematical procedures. The first approach inverts the usual question of 'what is the solution to this problem ' to, 'of what problem is this a solution '. Further, the existence of Grandi identities are identified and it is shown also that all of the infinite, convergent series contained within the infinitely large set may be expressed in terms of Grandi's series. All of the functions from which the corresponding series are generated are shown to possess an indefinite number of derivatives of increasing order, each of which is expressible as an infinite series, and are hence ideal candidates for expansion in terms of Taylor's series. 24 pp. Englisch.

Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Academic Paper from the year 2017 in the subject Physics - Other, grade: 1, , language: English, abstract: The surface of last scattering is regarded as a consequence of the Big Bang description of the origin of the observable universe. It is envisaged as a spherical surface from which all of the CMB photons emanate and centred on the Earth. Because of the opacity of the universe prior to the formation of this surface this taken to be the farthest redshift that may be observed.The discovery of the cosmic jerk was made, independently, by groups led by Schmidt and Perlmutter; the effect is shown clearly in their data as presented by Krauss, p85, [3]. It was found that approximately five billion years bp the expansion of the universe appeared to change suddenly from a state of deceleration to one of acceleration and is attributed to the entity called dark energy. It is not known whether this acceleration will persist into the indefinite future. Indeed, the future of the universe is a subject of much discussion, not to say, controversy.In this work the vacuum of the universe is modelled as a very large set of conjugate pairs of bi-modal, frequency-quantised, simple quantum harmonic oscillators, one having positive energy, the other, negative energy. Further, each pair of oscillators occupies a cubical enclosure of side equal to the wavelength corresponding to their current frequency, and related through the relationship, nil=c. The mode of action of the harmonic oscillators is explained in detail and is shown to exist in two modes, the sterile mode and the free vacuon mode, the former being the overwhelmingly-dominant state of the universe. According to the model developed here the universe, prior to inception was cold, dark and empty and had existed in this state into the indefinite past. Inception was induced by a quantum fluctuation casting the universe into a free vacuon mode and the baryonic and dark matters were formed cold during this phase. The light elements, which are taken to be evidence of a Big Bang are shown to be formed later by an isolated nuclear fusion event occurring during a free vacuon mode. The so-called surface of last scattering is also generated by the heating of mass during a free vacuon mode. The cosmic jerk is attributed to heating during a free vacuon mode and the CMB is the attenuated radiation from this event, the radiation from the nuclear fusion event and surface of last scattering being attenuated to below the level of detectability at the present time. 44 pp. Englisch.

A possible structure is proposed for the ensemble of cubes, and it is shown also that other configurations, on all scales can exist in the ensemble, even although the members of that collection are absolutely identical.The expansion of space is considered initially from the standpoint of a universe which is not accelerating, and equations are developed which relate to this 'coasting' condition, and, in which the Hubble parameter, H, is shown to be a function of time. These equations are extended by the inclusion of the deceleration parameter of cosmology, q, treating q as a parameter. 36 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Scientific Essay from the year 2018 in the subject Physics - Nuclear Physics, Molecular Physics, Solid State Physics, grade: 3.00, , language: English, abstract: It is shown that there may exist at least two different forms of dark matter fashioned from existing baryonic matter, specifically, neutrons. The structures developed are considerably more massive than the number of particles from which they are formed and are argued to be candidates for dark matter since they have no electrical charge, no electrons, hence no chemistry and no photonic emission. They can only interact with each other and other baryons through the agency of gravity. Further, one of the forms is much more likely to clump than the other and raises the possibility that there are large-scale formations of different types of the substance, one of which may more easily be disrupted than the other.This may present further challenges for astronomical experimenters in the task of observing and identifying dark matter, for, on a large scale the distribution of dark matter within, for example, a galaxy may be unique to that constellation. In addition, detection of these structures on a small scale, by the usual method of collision with other matter, may be rendered difficult, if not impossible, for the structures can only be accelerated to high speeds by interacting with intense gravitational fields. 24 pp. Englisch.
