What is known about the homology of the classifying space (realization of the nerve) of a category of modules over an algebra A? Anything special if A is the group algebra of a group G?? jim stasheff jds@math.unc.edu I am assembling a list of people interested in 2-cats or rather in applied 2-cat theory - e.g. classifying spaces thereof If interested in being added to the list... ===================================
