Let I be an ideal of a commutative ring A and B = A/Z. Given n 2 2, we characterize the vanishing of the Andrk-Quillen homology modules r-I,(A, B, W) for all B-modules W and for all p, 2 5 p 5 n, in terms of some canonical morphisms. As a corollary, we obtain a new proof of a theorem of And6 Finally

In this paper, we introduce a strategy for studying simplicial commutative algebras over general commutative rings R. Given such a simplicial algebra A, this strategy involves replacing A with a connected simplicial commutative k(˝)-algebra A(˝), for each ˝∈ Spec( 0A), which we call the connected co
