Holographic Einstein rings of non-commutative black holes
European Physical Journal C: Particles and FieldsWith the help of AdS/CFT correspondence, we derive the desired response function of QFT on the boundary of the non-commutative black hole. Using the virtual optical system with a convex lens, we obtain the Einstein rings of the black hole from the ...

The total graph and regular graph of a commutative ring
, 2009 Let R be a commutative ring. The total graph of R, denoted by T(Γ(R)) is a graph with all elements of R as vertices, and two distinct vertices x,y∈R, are adjacent if and only if x+y∈Z(R), where Z(R) denotes the set of zero-divisors of R.

On commutative idempotent rings
, 1995 We study the problem when a ring which is an extension of a commutative idempotent ring by a commutative idempotent ring is commutative. In particular, we answer Sands' question showing that the class of commutative idempotent rings whose every ...

The basic ring of a locally Artinian commutative Grothendieck category
, 1991 The context is that of a locally Artinian Grothendieck category---a Grothendieck category with a generating set of Artinian objects---which is, moreover, commutative in the sense that it has a generator with commutative endomorphism ring. C.

Valuations on a Commutative Ring [PDF]
, 1966 82 pagesThe purpose of this paper is to extend some results from the theory of valuations on a field to an arbitrary commutative ring with identity. The results obtained are well known when interpreted in the context of a field and comprise only a ...

Projective Modules and Polynomials over the Hurwitz Quaternions
MathematicsA theorem of Sheshadri (Proc. Nat. Acad. Sci. USA 44 (1958) 456–458) shows that, when Λ is a commutative principal ideal domain, finitely generated projective modules over the polynomial ring Λ[t] are all free. The ring Γ of Hurwitz quaternions, that is,

The essential ideal graph of a commutative ring
, 2018 Let [Formula: see text] be a commutative ring with identity. The essential ideal graph of [Formula: see text], denoted by [Formula: see text], is a graph whose vertex set is the set of all nonzero proper ideals of [Formula: see text] and two vertices ...

Advances in Commutative Ring Theory, Catania, Italy.
We study the category AtoMon of atomic monoids and atom-preserving maps, which is a (non-full) subcategory of the category Mon of monoids. We compute all limits and colimits, showing that AtoMon is both a complete and cocomplete category.

Moduli Spaces of Commutative Ring Spectra
, 2003 Let E be a homotopy commutative ring spectrum, and suppose the ring of cooperations E#E is flat over E# . We wish to address the following question: given a commutative E# -algebra A in E#E-comodules, is there an E# -ring spectrum X with E#X = A as
