Translation-finite sets, and weakly compact derivations from $\lp{1}(\Z_+)$ to its dual

Yemon Choi, Matthew J. Heath

We characterize those derivations from the convolution algebra $ℓ^{1} (Z_{+})$ to its dual which are weakly compact. In particular, we provide examples which are weakly com…

Uniform bounds for point cohomology of $ℓ^{1} (Z_{+})$ and related algebras

Yemon Choi

It is well-known that the point cohomology of the convolution algebra $ℓ^{1} (Z_{+})$ vanishes in degrees 2 and above. We sharpen this result by obtaining splitting maps wh…
