Meier's ardor

from Wikipedia, the free encyclopedia

Meier "Maks" Eidelheit (born July 16, 1910 in Janów ; † March 1943 ) was a Polish mathematician .

Meier Eidelheit graduated from high school in 1929 and then studied mathematics at the natural science faculty in Lemberg , which he completed in 1933 with a thesis on the theory of summation. In 1938 he was with the thesis about the solvability of a linear system of equations with infinitely many unknowns at the Jan Kazimierz- Lviv University under Stefan Banach doctorate . From 1933 to 1939 he held private lectures, from January 31, 1939 he held an assistant professorship in analysis , and from March 21, 1941 he was a candidate for the academic rank of professor. His main area of ​​work was functional analysis . Based on his 1936 work on the theory of convex sets in linear normalized spaces , geometric versions of the separation theorem are also referred to as Eidelheit's separation theorem. A theorem about the solvability of certain infinite systems of equations in Fréchet spaces also bears his name.

Meier Eidelheit was a victim of the Holocaust in March 1943 . The article by Meier Eidelheit Quelques remarques sur les fonctionelles linéaires , published posthumously in Volume 10 of the Studia Mathematica , is preceded by the following lines: “L'auteur de ce travail a été assassiné par les Allemands en mars de 1943. Le manuscrit qu'il fut parvenir à la Rédaction en 1941 a été retrouvé récemment entre les papiers laissés par S. Banach. ”(German: The author of this work was murdered by the Germans in March 1943. The manuscript, which reached the editorial office in 1941, was recently among those published by S. Banach found the writings left behind.)
