The center of SL2 tilting modules
Published 21 Apr 2020 in math.RT and math.QA | (2004.10146v2)
Abstract: In this note we compute the centers of the categories of tilting modules for G=SL2 in prime characteristic, of tilting modules for the corresponding quantum group at a complex root of unity, and of projective GgT-modules when g=1,2.
