On a Splitting Theorem of Gaschütz
Published online by Cambridge University Press: 20 January 2009
Extract
Let G be any finite group, and p any prime number. (All groups to be considered here are finite, and we assume this without further comment.) We denote by Kp(G) the unique smallest normal subgroup of G for which the quotient G/Kp(G) is a p-group. G/Kp(G) is called the p-residual of G. W. Gaschütz (2, Satz 7) has proved the following
Theorem. Set K = Kp(G). If the Sylow p-subgroups of K are abelian, then G splits over K.
