Robert Remak (Mathematician) (Paperback)

High Quality Content by WIKIPEDIA articles! Robert Erich Remak (born February 14, 1888 in Berlin; died November 13, 1942 in Auschwitz) was a German mathematician. He is chiefly remembered for his work in group theory (Remak decomposition). His other interests included algebraic number theory, mathematical economics and geometry of numbers. Robert Remak was the son of the neurologist Ernst Julius Remak. Robert Remak studied at Humboldt University of Berlin under Ferdinand Georg Frobenius and received his doctorate in 1911. His dissertation, Uber die Zerlegung der endlichen Gruppen in indirekte unzerlegbare Faktoren ("On the decomposition of a finite group into indirect indecomposable factors") established that any two decompositions of a finite group into a direct product are related by a central automorphism. A weaker form of this statement, uniqueness, was first proved by Joseph Wedderburn in 1909.
