This leads to an explicit formula for the Dutta multiplicity, and it is shown that a weaker version of Serre's vanishing conjecture holds if only chi(F(X)) = p^{dim R}chi(X) for all bounded complexes X of finitely generated, projective modules with finite length homology.Revised (simplified) version. 12 pagesCommutative Algebra13A35, 13D22, 13H15, 14F17Diagonalizing the Frobeniustext
