Equivariant version of cyclic versus de Rham (co)homology of commutative algebras?
Let $A$ be a commutative algebra that is a $g$-module, for some Abelian Lie algebra $g$. The primary example of my interest is when $A$ is the ring of functions over an affine variety, say $\mathbb{C} …

Hochschild and cyclic cohomology of commutative algebra?
I'm wondering how to compute the Hochschild cohomology ${\rm HH}^n(A,A)$ and the cyclic cohomology ${\rm HC}^n(A)$ where $A = \mathbb{C}[t_i]$ is the algebra of polynomials in a finite set of commutat …
