Query: Changement de base pour les foncteurs Tor   We give in this paper an isomorphism theorem between derived functors over
categories of modules.There is a nice class of categories that gives examples
in which this theorem applies for a special construction. This leads us to a
new interpretation of a theorem of Pirashvili and Richter about cyclic homology
and Hochschild homology.
