Weight conjectures for Parker--Semeraro fusion systems

Representation Theory 2024-07-11 v1 Group Theory

Abstract

We prove that the Parker--Semeraro systems satisfy six of the nine Kessar--Linckelmann--Lynd--Semeraro weight conjectures for saturated fusion systems. As a by-product we obtain that Robinson's ordinary weight conjecture holds for the principal 33-block of Aut(G2(3))(G_2(3)), the principal 55-blocks of HNHN, BMBM, Aut(HN)(HN), LyLy, the principal 77-block of MM, and the principal pp-blocks of G2(p)G_2(p) for p3p\geq 3 .
