Excerpt from Acta Mathematica, 1894, Vol. 18
Si une telle multiplicité satisfait à. Une ou plusieurs équations aux dérivées partielles, entre les et, les 2 et leurs dérivées, elle satisfait aussi aux équations qui s'en déduisent par différentiation. En s'élevant aux ordres supérieurs, on obtient de la sorte un nombre illimité d'équations; si on ne considère pas celles-ci comme distinctes des premières, il y a lieu de se demander s'il peut exister des systèmes comprenant un nombre illimité d'équations ainsi distinctes, et s'il peut exister des multiplicités définies comme solutions de pareils systèmes illimités d'équations.

Paperback. Zustand: New. Print on Demand. This book explores the theory of differential invariants associated with continuous groups of transformations. As an extension of Lie's theories on transformation groups, the author establishes how differential invariants can be deduced from the equations of definition of a group. The concept of a 'reduced form' is discussed and it is shown how differential invariants can help obtain new parameters for invariant transformations. The author applies these principles to determine the invariants of a surface, according to both conformal transformations of space and projective transformations, and examines invariants previously obtained by a different method to solve a problem treated by Roger Liouville. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
