Abstract
We reformulate the persistent (co)homology of simplicial filtrations, viewed from a more algebraic setting, namely as the (co)homology of a chain complex of graded modules over polynomial ring . We also define persistent (co)homology of groups, associative algebras, Lie algebras, etc. \par Then we obtain formulas for tensor powers where is a persistence module. We discuss the cyclic and dihedral powers of persistence modules, and more generally quotients of by a group action.
