Projection invariant $t$-Baer and related modules
Abstract
UDC 512.5
We investigate the concepts of projection invariant $t$-extending modules and projection invariant $t$-Baer modules, which are generalized to those $\pi$-extending and $t$-Baer notions, respectively. Several structural properties are obtained and some applications are developed. It is proved that the $\pi$-$t$-extending modules and $\pi$-$t$-e. Baer modules are connected with each other. Moreover, we obtain a characterization for $\pi$-$t$-extending modules relative to the annihilator conditions.
