Simplicial cohomology of augmentation ideals in $ℓ^{1} (G)$

Yemon Choi

Let $G$ be a discrete group. We give a decomposition theorem for the Hochschild cohomology of $ℓ^{1} (G)$ with coefficients in certain $G$ -modules. Using this we show that if $G$ i…

Hochschild homology and cohomology of {\ell}^1({\mathbb Z}_+^k)

Yemon Choi

Building on the recent determination of the simplicial cohomology groups of the convolution algebra $ℓ^{1} (Z_{+}^{k})$ [Gourdeau, Lykova, White, 2005] we investigate what…
