**Abstract:
**In this talk, we consider
the conjecture which states that if G=(Z/pZ)^r and X
is a finite free G-CW-complex, then the rank of H_*(X , Z/pZ)
over Z/pZ is at least 2^r. We formulate the algebraic
version of the
conjecture for p=2 and prove its equivalence with a conjecture concerning differential graded modules over
polynomial rings.
