O článku:
Let ${\mathcal A}$ be a Banach algebra and let ${\mathcal M}$ be a unital Banach algebra. For a homomorphism $Φ$ from $\mathcal{A}$ into $\mathcal{M}$, we consider ${\mathcal M}$ as a Banach right ${\mathcal A}$-module and investigate when ${\mathcal M}$ is a retract of ${\mathcal A}$ with respect to $Φ$. We also give characterizations of admitting vector-valued invariant $Φ$-means in terms of projectivity and injectivity. Finally, we apply these results to abstract Segal algebras.
