A construction of the universal classes for algebraic groups with the twisting spectral sequence

Abstract

In this article, we apply some ideas developped by M. Chałupnik to the framework of strict polynomial bifunctors. This allows us to get a new proof of the existence of the `universal classes' originally constructed by the author.
