Last week we introduced an obstruction theory for the existence and uniqueness of a solution to the gluing problem for a biset functor defined on the sections of a finite group G. The obstruction groups for this theory are the reduced cohomology groups of a category whose objects are the sections (U,V) of G with V not equal to 1, and whose morphisms are defined as a generalization of morphisms in the orbit category. This week we will show how these obstruction groups can be calculated using the work of Jackowski-Slominska on isotropy presheaves, and a theorem of Bob Oliver on the cohomology groups of the Quillen category of a finite group. This is a joint work with Olcay Coşkun.
