Higher Dimensional Peiffer Elements in Simplicial Commutative Algebras

Z. Arvasi and T. Porter

Let E be a simplicial commutative algebra such that E_n is generated by degenerate elements. It is shown that in this case the n^th term of the Moore complex of E is generated by images of certain pairings from lower dimensions. This is then used to give a description of the boundaries in dimension n-1 for n = 2, 3, and 4.
