Separation and excision in functor homology
Aurélien Djament, Antoine Touzé
We prove separation and excision results in functor homology. These results explain how the global Steinberg decomposition of functors proved by Djament, Touz{é} and Vespa behaves…

The homology of additive functors in prime characteristic
Aurélien Djament, Antoine Touzé
We compute certain Ext and Tor groups in the category of all functors from an Z/p-linear additive category A to vector spaces in terms of Ext and Tor computed in the full subcatego…
