Dimitrie Pompeiu (1873-1954)

Romanian mathematician. Professor at the Universities of Jassy, Bucharest and Cluj. Member of the Romanian Academy. His contributions were mainly in the field of mathematical analysis, the complex variable functions theory and rational mechanics. His doctoral thesis (done in Paris in 1905), to be famous since then, demonstrated by exemplification that there existed analytical functions that are continuous on the set of their singularities. He was the mathematician who introduced the notion of areolar derivative, to become wide-spread among his students; he also introduced the notion of the two sets distance and built real, inconsistent functions of which derivative may be cancelled anytime, the so-called Pompeiu's functions. He founded the mathematics school of partial differential equations theory and the mechanics school.

Main work: "On the Continuity of Complex Variable Functions" (1905).
