Walter theorem
In mathematics, the Walter theorem, proved by , describes the finite groups whose Sylow 2-subgroup is abelian. used Bender's method to give a simpler proof.
Statement.
Walter's theorem states that if "G" is a finite group whose 2-sylow subgroups are abelian, then "G"/"O"("G") has a normal subgroup of odd index that is a product of groups each of which is a 2-group or one of the simple groups PSL("q") for "q" = 2 or "q" =
Marion Walter
Marion Walter (born July 30, 1928 in Berlin, Germany) is a mathematician who retired as Professor of Mathematics at University of Oregon in 1994. There is a theorem named after her, called Marion Walter's theorem.
Education and early life.
Born in Germany in 1928, she left on a "Kindertransport" to England where she attended a boarding school.
After she left school in December 1944 the school's only mathematics teacher resigned and since it was difficult to find a replacement during
