The structure of rings via automorphism-invariant modules
Speaker: Trương Công Quỳnh (Da Nang Uni. of Education)

Time: 9:30 -- 11:00, Wed. June 22, 2022

Abstract: A module is called automorphism-invariant if it is invariant under all automorphisms of its injective hull. In this talk, we give some properties of these modules and the structure of rings via automorphism-invariant modules. In particular, we give some characterizations of rings in which every ideal is automorphism-invariant and quasi-Frobenius rings via automorphism-invariant rings.
