NCTS(South) Seminar

DATE 2013-07-08　15:10-16:00

PLACE R204, 2F, NCTS, NCKU

SPEAKER Dr. Heiko Dietrich（School of Mathematical Sciences, Monash University）

TITLE Investigating Radical Subgroups of Finite Groups

ABSTRACT A subgroup R of a finite group G is p-radical (p a prime) if R = O_p(N_G(R)), that is, if R is the largest normal p-subgroup in its normaliser in G. Radical subgroups play an important role in group theory and modular representation theory. In this talk we discuss some aspects related to radical subgroups, for example, their classification, and the essential rank of finite groups. This is joint (and ongoing) work with Jianbei An (University of Auckland) and Shih-Chang Huang.
