Hecke operators on Hilbert-Siegel modular forms
, 2007 We define Hilbert-Siegel modular forms and Hecke "operators" acting on them. As with Hilbert modular forms, these linear transformations are not linear operators until we consider a direct product of spaces of modular forms (with varying groups), modulo ...

Weak Compactness of Multiplication Operators on Spaces of Bounded Linear Operators.
MATHEMATICA SCANDINAVICA, 1992 Let \(E\) be a Banach space and let \(A\) and \(B\) be bounded operators on \(E\). This paper studies the problem of the weak compactness of the linear multiplication operator \(A\wedge B: S\mapsto BSA\) from \(L(E)\) into \(L(E)\) (\(A,B\neq 0\)).

An intracellular transporter mitigates the CO2‐induced decline in iron content in Arabidopsis shoots
FEBS Letters, EarlyView.This study identifies a gene encoding a transmembrane protein, MIC, which contributes to the reduction of shoot Fe content observed in plants under elevated CO2. MIC is a putative Fe transporter localized to the Golgi and endosomal compartments. Its post‐translational regulation in roots may represent a potential target for improving plant nutrition ...

Spaces generated by the cone of sublinear operators
Karpatsʹkì Matematičnì Publìkacìï, 2018 This paper deals with a study on classes of non linear operators. Let $SL(X,Y)$ be the set of all sublinear operators between two Riesz spaces $X$ and $Y$. It is a convex cone of the space $H(X,Y)$ of all positively homogeneous operators.

Properties of Fuzzy Closed Linear Operator [PDF]
Engineering and Technology Journal, 2019 In this paper we recall the definition of fuzzy norm of a fuzzy bounded linear operator and the fuzzy convergence of sequence of fuzzy bounded linear operators in order to prove the uniform fuzzy bounded theorem and fuzzy open mapping theorem.

Reflexivity defect of spaces of linear operators
Linear Algebra and its Applications, 2009 Let \(V,W\) be linear spaces over a commutative field \(F\). Let \({\mathcal L}(V,W)\) denote the space of linear operators. For a subspace \({\mathcal S} \subset {\mathcal L}(V,W)\) and for an integer \(k>0\), the \(k\)-reflexive closure \(\text{Ref}_k({\mathcal S})\) is the set of operators \(T\) such that for any \(x=x_1\otimes x_2\otimes\dots ...

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes
FEBS Letters, EarlyView.The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Positive operators and approximation in function spaces on completely regular spaces
International Journal of Mathematics and Mathematical Sciences, 2003 We discuss the approximation properties of nets of positive linear operators acting on function spaces defined on Hausdorff completely regular spaces. A particular attention is devoted to positive operators which are defined in terms of integrals with ...

On the structure of spaces of vector-valued Lipschitz functions
, 2016 We analyse the strong connections between spaces of vector-valued Lipschitz functions and spaces of linear continuous operators. We apply these links to study duality, Schur properties and norm attainment in the former class of spaces as well as in their

Partial *-Algebras of Closed Linear Operators In Hilbert Space
Publications of the Research Institute for Mathematical Sciences, 1985 Given a dense domain \mathcal D of a Hilbert space, we consider the class of all closed operators which, together with their adjoint, have \mathcal D in their domain.
