Abstract
Motivated by the cohomology theory of loop spaces, we consider a special class of higher order homotopy commutative differential graded algebras and construct the filtered Hirsch model for such an algebra . When with coefficients and the symmetric Massey products with have a finite order (whenever defined). However, if is a field of characteristic zero, is defined and vanishes in for all . If is an odd prime, the Kraines formula lifts to Applications of the existence of polynomial generators in the loop homology and the Hochschild cohomology with a -algebra structure are given.
