The hierarchies of identities and closed products for multiple complexes

Abstract

We consider infinite ${\mathbb{Z}}_{\mathbb{Z}}$-index complexes $\mathcal{C}$ of spaces with elements depending on a number of parameters, complete with respect to a linear associative regular inseparable multilinear product. The existence of nets of vanishing ideals of orders of and powers of differentials is assumed for subspaces of $\mathcal{C}$-spaces. In the polynomial case of orders and powers of the differentials, we derive the hierarchies of differential identities and closed multiple products. We prove that a set of maximal orders and powers for differentials, differential conditions, together with coherence conditions on indices of a complex $\mathcal{C}$ elements generate families of multi-graded differential algebras.
