"The
Puig category and

Brauer characters II"

By

Daghan Volkan YAYLIOGLU

Abstract: First defined by J. Green (1968), a $G$-algebra is a powerful tool
to study modular representation theory, and central to the $G$-algebra theory
is pointed groups, which are first introduced by Puig
(1981). There is a bijection between local pointed
groups and irreducible modules which is the motivation of our aim, that is, to
carry the subgroup relation between two local pointed groups to Brauer characters. This talk will develop a subset of
$G$-algebra theory before proving two elementary results in this direction.
