Squashed entanglement is a measure for the entanglement of bipartite quantum states. In this paper we present a lower bound for squashed entanglement in terms of a distance to the set of separable states. This implies that squashed entanglement is faithful, that is, it is strictly positive if and only if the state is entangled. We derive the lower bound on squashed entanglement from a lower bou...
let $mathcal a$ and $mathcal b$ be unital rings, and $mathcal m$ be an $(mathcal a, mathcal b)$-bimodule, which is faithful as a left $mathcal a$-module and also as a right $mathcal b$-module. let ${mathcal u}=mbox{rm tri}(mathcal a, mathcal m, mathcal b)$ be the triangular ring and ${mathcal z}({mathcal u})$ its center. assume that $f:{mathcal u}rightarrow{mathcal u}$ is...
With every (strict or normal) unital endomorphism of the algebra of all adjointable operators on a Hilbert module there is associated a correspondence (that is, a Hilbert bimodule) such that the endomorphism can be recovered as amplification of the identity representation with that correspondence. In these notes we show the converse of this statement in the case of strongly full W–correspondenc...
Triple extraction is an essential task in information for natural language processing and knowledge graph construction. In this paper, we revisit the end-to-end triple sequence generation. Since generative may struggle to capture long-term dependencies generate unfaithful triples, introduce a novel model, contrastive with transformer. Specifically, single shared transformer module encoder-decod...
let a be a banach algebra and e be a banach a-bimodule then s = a e, the l1-direct sum of a and e becomes a module extension banach algebra when equipped with the algebras product (a; x):(a′; x′) = (aa′; a:x′ + x:a′). in this paper, we investigate △-amenability for these banach algebras and we show that for discrete inverse semigroup s with the set of idempotents es, the module extension bana...
let $r$ be a commutative ring with identity and $m$ be a finitely generated unital $r$-module. in this paper, first we give necessary and sufficient conditions that a finitely generated module to be a multiplication module. moreover, we investigate some conditions which imply that the module $m$ is the direct sum of some cyclic modules and free modules. then some properties of fitting ideals of...
Let $(R,\mathfrak m)$ be a commutative Noetherian local ring. There is variety of nice results about approximately Cohen-Macaulay rings. These were done by Goto. In this paper we prove some these for modules and generalize the concept rings to modules. It seen that when $M$ an module, any proper ideal $I$ have $grade(I,M) \geq \dim_R M -\dim_R M/IM -1$. Specially $R$ itself, obtain interval $gr...
