Abstract :
A module M is said to be an automorphism liftable module if
for each submodule N of M, every automorphism of the quotient M/N can
be lifted to an endomorphism of M. In this work, some properties of automorphism liftable modules are investigated. Also, characterization for some
special rings such as perfect, semiperfect and uniserial are given by using automorphism liftable modules.
Keywords :
