WebAn excisive functor is one sending pushout squares to pullback squares. Given such a functor F, we obtain a Ω-spectrum in the classical sense by defining X n = F (Σ n S 0), and the structural morphisms come from the property F (Σ n S 0) = Ω F (Σ n-1 S 0). Conversely, given any Ω-spectrum one can extend this to a functor on all of * fin. Webspectra and Drinfeld centers Kent Vashaw Setting: finite tensor categories A monoidal category (C,⊗,1) is a finite tensor category if it is an abelian k-linear monoidal category such that −⊗−is bilinear on spaces of morphisms; every object has finite length; Hom(A,B) is finite-dimensional; 1 is simple; there are enough projectives;
