Jordan and Local Multipliers on Certain Banach Algebras are Multipliers [PDF]
Sahand Communications in Mathematical Analysis, 2023 We prove that every continuous Jordan multiplier $T$ from a $C^*$-algebra $A$ into a Banach $A$-bimodule $X$ is a multiplier. We also characterize continuous linear maps on $C^*$-algebras and standard operator algebras determined by preserving some ...

Characterization of n-Jordan multipliers on rings [PDF]
Journal of Mahani Mathematical ResearchOur main result states that every Jordan multiplier $T$ from a commutative ring $\mathcal{R}$ into a faithful $\mathcal{R}$-bimodule $M$ with characteristic different from $2$, is a multiplier.

Quasi-multipliers and quasi Jordan multipliers [PDF]
AUT Journal of Mathematics and ComputingWe show that every quasi-multiplier $\phi:L^1(G)\times L^1(G)\longrightarrow L^1(G)$, where $G$ is a locally compact group, is of the form $$\phi(f,g)=f\star \mu\star g,\ \ \ \ \ f,g\in L^1(G),$$ for a unique ...

Surveys in Mathematics and its Applications, 2018 Let A be a Banach algebra, X be a Banach left A-module and n ≥ 2 be an integer. A bounded linear operator T: A → X is called an n-Jordan multiplier if for each a ∈ A, T(an)=a· T(an-1).

A reconstruction method for anisotropic universes in unimodular F(R)-gravity
European Physical Journal C: Particles and Fields, 2022 An extension of unimodular Einsteinian gravity in the context of F(R) gravities is used to construct a class of anisotropic evolution scenarios. In unimodular GR the determinant of the metric is constrained to be a fixed number or a function.

International Journal of Business and Society, 2022 This study aimed to analyze the impacts of government expenditure and the public revenues on economic growth via the estimation of the fiscal multipliers for the period of (1975-2017). Also, the study analyzed the value and effects of the determinants of this multiplier, namely the openness of trade, public debt, the exchange rate, and the size of ...

Ghost-free F(R) gravity with Lagrange multiplier constraint
Physics Letters B, 2017 We propose two new versions of ghost-free generalized F(R) gravity with Lagrange multiplier constraint. The first version of such theory for a particular degenerate choice of the Lagrange multiplier, corresponds to mimetic F(R) gravity.

, 2022 Let R be a prime ring of characteristic not equal to 2, U be its Utumi quotient ring and C be the extended centroid of R. Let ϕbe a multilinear polynomial over C, which is not central valued on R and F, G be two b-generalized skew derivations on R. The purpose of this article is to describe all possible forms of the b-generalized skew derivations F and

A constrained Wasserstein gradient flow for aggregation–diffusion dynamics with application to economic adjustment [PDF]
Royal Society Open ScienceWe study a class of constrained aggregation–diffusion dynamics formulated as a Wasserstein gradient flow with a linear moment constraint. The model describes the evolution of a probability density on R+ governed by a Fokker–Planck equation with potential,
