Title: Classification of blocks and open conjectures
Abstract: Donovan’s conjecture predicts that given a p-group D there are only finitely
many Morita equivalence classes of blocks of group algebras with defect
group D. While the conjecture is still open for a generic p-group D, it
has been proven in many special cases. A harder question is the one to
actually classify Morita equivalence classes in a given situation, i.e. to have a
complete list of blocks that can occur determined up to Morita equivalence.
In this talk, I will introduce the topic, give the relevant definitions and
then roughly describe the process of classifying blocks, with a focus on the
methodology and the tools normally needed to obtain such a result. Then
I will focus on some applications of having such a list, mentioning some
(perhaps surprising) difficulties that can arise in verifying certain classic
modular representation theory conjectures, even when a complete list of
blocks is given.
