Abstract
The main objective of this thesis is twofold. First, we aim to
study some extended injectivities of graded modules, such as
F-injectivity, P- injectivity, and mininjectivity. Second, we aim to
investigate the structure of graded quasi-Frobenius rings. Actually,
we provide characterizations of graded quasi-Frobenius rings in
terms of extended graded injectivities of graded rings.
