ANDRE-QUILLEN HOMOLOGY IN DEGREE-5

[摘要] Given two commutative A-algebras B and C and a B x (A) C-module W, the modules H(n)(A, B, C, W) are useful for comparing the ordinary Andre-Quillen homology modules H(n)(A, B, W) and H(n)(C, B x (A)C, W); they have been studied for small values of n. In this paper, we focus our attention on the module H5(A, B, C, B x (A)C). As a corollary of our computations, we obtain some new results in the theory of the cotangent complex.
