WebRham’s theorem will reduce to invoking these axioms in both cohomology theories. 2. Homotopy invariance of de Rham cohomology Our next two results, homotopy invariance and the Mayer-Vietoris sequence for de Rham cohomology, requres us to introduce elements in the language of homo-logical algebra. This will capture the important … Webtheories and for many purposes these seem to be adequate, at least for problems within the realm of stable homotopy theory. In particular, in this paper we will show that there are stable operations defined within a suitable version of elliptic cohomology and which restrict on the coefficient ring to the classical Hecke operators on modular ...
