Permutation of edges in mutation reduction of pointed Brauer trees
Reut Frenkel-Mayzlish, Mary Schaps, Zehavit Zvi
Aihara developed an algorithm for Brauer tree algebras, which we call a mutation reduction, for getting from a Brauer tree algebra to the simpler Brauer star algebra using a sequen…
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…
Elementary equivalences for blocks with normal elementary abelian defect group of rank 2
Mary Schaps, Zehavit Zvi
We consider the effect of performing an elementary equivalence as defined by Okuyama on a group block of form , for a field of characteristic .…
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…
