A computer algebra system for the study of commutativity up-to-coherent homotopies

02/15/2021 ∙ by Anibal M. Medina-Mardones, et al. ∙ 0

The Python package ComCH is a lightweight specialized computer algebra system that provides models for well known objects, the surjection and Barratt-Eccles operads, parameterizing the product structure of algebras that are commutative in a derived sense. The primary examples of such algebras treated by ComCH are the cochain complexes of spaces, for which it provides effective constructions of Steenrod cohomology operations at all prime.
