1894. TRUE 1st edition of the French mathematician Pierre Cousin's doctoral thesis, published the following year in Acta Mathematica. Ownership stamp "F. Heymann," likely Franz Ferdinand Heyman (1924-2005), a British physicist who served as Quain Professor at University College London. He was featured in Who's Who in British Scientists, Who's Who in Atoms and Who's Who in Technology. Offered here is Cousin's thesis on the additive problem, or the two "Cousin problems," "two questions in several complex variables, concerning the existence of meromorphic functions that are specified in terms of local data" (Wikipedia). Cousin's work here has particular application to classical global function theory. Cousin who succeeded in solving it for products of planar domains by systemically iterating one variable techniques based on the Cauhy integral formula. in his honor the decomposition problem is often referred to as the additive cousin problem" (Range, Complex Analysis: A Brief Tour into Higher Dimensions).
