Cohomology theories
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 ...

In this paper I shall introduce a generalization of the notion of topological abelian group which leads to generalized cohomology theories.

Web1 day ago · We study sympathetic (i.e., perfect and complete) Lie algebras. Among other topics they arise in the study of adjoint Lie algebra cohomology. Here a motivation comes from a conjecture of Pirashvili, which says that a finite-dimensional complex perfect Lie algebra is semisimple if and only if its adjoint cohomology vanishes.
