On extension of characters from normal subgroups
Published online by Cambridge University Press: 20 January 2009
Extract
In what follows, character means irreducible complex character.
Let G be a finite group and let % be a character of a normal subgroup N. If χ extends to a character of G then χ is stabilised by G, but the converse is false. The aim of this paper is to prove the following theorem which gives a sufficient condition for χ to be extended to a character of G.
