Title: Gluing biset functors

Abstract: We develop an obstruction theory for the existence and uniqueness of a solution to the gluing problem for a biset functor. The obstruction groups for this theory are reduced cohomology groups of a category of sections. Using this obstruction theory, we calculate the obstruction group for the Dade group of a p-group when p is odd. This is a joint work with Ergün Yalçın.
