Generalized injectivity of Banach modules
M Fozouni - arXiv preprint arXiv:1502.04506, 2015 - arxiv.org
In this paper, we study the notion of $\phi $-injectivity in the special case that $\phi= 0$. For
an arbitrary locally compact group $ G $, we characterize the 0-injectivity of $ L^{1}(G) $ as a …

Homological properties of modules over semigroup algebras
P Ramsden - Journal of Functional Analysis, 2010 - Elsevier
Let S be a semigroup. In this paper we investigate the injectivity of ℓ1 (S) as a Banach right
module over ℓ1 (S). For weakly cancellative S this is the same as studying the flatness of the …
