Efficiency of mutation reduction for Brauer trees
Zehavit Zvi
Brauer tree algebras are important and fundamental blocks in the modular representation theory of groups. Aihara develped an algorithm, which we call a mutation reduction, for gett…

Mutations and Pointing for Brauer Tree Algebras
Mary Schaps, Zehavit Zvi
Brauer tree algebras are important and fundamental blocks in the modular representation theory of groups. In this research, we present a combination of two main approaches to the t…
