Abstract
Given two finitely presentable Abelian categories
and
, we outline a construction of an Abelian category of functors from
to
, which has nice 2-categorical properties and provides an explicit model for a stable category of stable functors between the derived categories of
and
. The construction is absolute, so it makes it possible to recover not only Hochschild cohomology but also Mac Lane cohomology.
