For a given ideal I of a commutative ring ç
A,B = A/I, the vanishing of the second André-Quillen (co)homology functor H2(A,B,*) is characterized in terms of the canonical homomorphism a:S(I)->R(I) from the symmetric
algebra of the ideal I onto its Rees algebra. This is done by introducing a Koszul
complex that characterizes commutative graded algebras which are symmetric
algebras.
