All rings considered in this paper are assumed to be commutative with identities. A ring $ R
$ is a $ Q $-ring if every ideal of $ R $ is a finite product of primary ideals. An almost $ Q …

In this thesis we develop results concerning strongly group-graded lk-algebras. Chapter 1 is
mainly expository: we set up a careful treatment of well-known facts and definitions …

Let k be a field and let Λ be a finite dimensional k-algebra. We prove that every bounded
complex V• of finitely generated Λ-modules has a well-defined versal deformation ring R (Λ …

We consider a class of self-injective special biserial algebras ΛN over a field K and show
that the Hochschild cohomology ring of dΛN is a finitely generated K-algebra. Moreover, the …

Let R be a ring with identity and J (R) denote the Jacobson radical of R, ie, the intersection of
all maximal left ideals of R. A ring R is called J-symmetric if for any a, b, c∈ R, abc= 0 …

In this paper, it has been proved that for a Noetherian ring R and an automorphism σ of R,
an associated prime ideal of R [x, σ] or R [x, x− 1, σ] is the extension of its contraction to R …

Given a group G acting on a ring R via α: G→ Aut (R), one can construct the skew group ring
R* αG. Skew group rings have been studied in depth, but necessary and sufficient …

All rings have an identity, all homomorphisms map identities to identities, all
homomorphisms on algebras over fields are algebra homomorphisms. A ring R is a quotient …
