Modules $M$ such that $\Ext_R^1(M,-)$ commutes with direct limits

Simion Breaz

We will use Watts's theorem together with Lenzing's characterization of finitely presented modules via commuting properties of the induced tensor functor in order to study commutin…

Direct products and the contravariant hom-functor

Simion Breaz

We prove in ZFC that if $G$ is a (right) $R$ -module such that the groups $\Hom_R(\prod_{i\in I}G_i,G)$ and $\prod_{i\in I}\Hom_R(G_i,G)$ are naturally isomorphic for all families o…
