"Finding Idempotents of the Trivial Source Algebra"
Abstract: The primitive idempotents of the Burnside algebra of a finite group can be computed explicitly by a formula found by Gluck and later independently by Yoshida. Using this, Bouc and Thevenaz obtained a formula for the primitive idempotents of the trivial source algebra. In this talk, for a concrete example, we shall calculate the primitive idempotents directly and we shall investigate whether it is possible to obtain a simpler formula.
