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
π
-extending and
t
-Baer notions, respectively. Several structural properties are obtained and some applications are developed. It is proved that the
π
-
t
-extending modules and
π
-
t
-e. Baer modules are connected with each other. Moreover, we obtain a characterization for
π
-
t
-extending modules relative to the annihilator conditions.
