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 …

In this paper, some homological notions of Banach A-modules such as ϕinjectivity, 0-
injectivity and character injectivity are discussed, where ϕ is a non-zero multiplicative linear …

Let A be a Banach algebra and let ϕ be a nonzero character on A. For a locally compact
group G, let the group algebra L 1 (G) be a closed two-sided ideal in A. In this paper, we aim …

Let be a Banach algebra and let φ be a non-zero character on. We introduce and study the
notions φ-injectivity and φ-projectivity for Banach-modules ℰ by modifying the injectivity and …

In this paper, we investigate the notion $\phi $-injectivity for Banach $ A $-modules, where
$\phi $ is a character on $ A. $ We obtain some hereditary properties of $\phi $-injectivity for …

In this note we discuss some necessary and some sufficient conditions for the relative
injectivity of the-module, where is a locally compact Hausdorff space. We also give a Banach …
