Eberhard Melchior

from Wikipedia, the free encyclopedia

Eberhard Melchior (born November 27, 1912 in Dresden ; † unknown) was a German mathematician.

Life

Melchior was the son of a teacher. After graduating from high school in Dresden-Neustadt, he studied mathematics from 1932 in Göttingen, at the TH Dresden and the University of Berlin, where he received his doctorate in 1937 (investigations into a problem from the theory of configurations). While the dissertation was praised by Ludwig Bieberbach (opus valde laudabile), he had to repeat the doctoral examination (Rigorosum) and only came up with a satisfactory in mathematics (co-supervisor was Erhard Schmidt ). In a work published in 1940, he gave the first known proof of Sylvester-Gallai's theorem , although this was not known to wider circles at the time. More precisely, he proved the projective-equivalent (dual) formulation of the theorem using Euler's polyhedron theorem. In this context, an inequality is named after him.

A total of three publications by him are known. Two of them were published in the journal Deutsche Mathematik by Ludwig Bieberbach.
