Robert Remak (mathematician)

Erich Robert Remak ( born February 14, 1888 in Berlin, † November 13, 1942 in Auschwitz ) was a German mathematician. He is known for the Remaksche decomposition of a group, also Remak worked in number theory, potential theory and the geometry of numbers. Robert Remak was a son of neurologist Ernst Julius Remak.

Robert Remak studied at the Berlin University of Ferdinand Georg Frobenius and his doctorate there in 1911. After his habilitation he worked 1929-1933 as a lecturer at the Berlin University. After the " seizure of power" by Hitler but Remak lost his position because of his Jewish origin. After the November Pogrom of 1938 Remak was arrested and was detained for several weeks in the Sachsenhausen concentration camp near Berlin. After his release he emigrated to the Netherlands, where he was but was arrested after the occupation by German troops in 1942 again deported to Auschwitz and murdered.

His doctoral thesis about the decomposition of finite groups in indirect indecomposable factors includes a frequently after him, Wolfgang Krull and Otto Schmidt Yulievich named set of group theory ( which has already been proved by Joseph Wedderburn 1909). Remak also dealt with algebraic number theory.
