A brief description of operators associated to the quantum harmonic oscillator on Schatten-von Neumann classes [PDF]

open access: yes, 2018
In this note we study pseudo-multipliers associated to the harmonic oscillator (also called Hermite multipliers) belonging to Schatten classes on $L^2(\mathbb{R}^n)$.

Important Structural Linkages in the Process of Income Circulation Defined by SAMs

open access: yesComparative Economic Research, 2014
The main aim of this paper is to present the analytical possibilities offered by Social Accounting Matrices as regards economic policy. These matrices are synthetic presentations of income flows in the economy, described by the international statistical ...

Multidimensional operator multipliers

open access: yes, 2008
We introduce multidimensional Schur multipliers and characterise them generalising well known results by Grothendieck and Peller. We define a multidimensional version of the two dimensional operator multipliers studied recently by Kissin and Shulman. The

On the consequences of a Mihlin-H\"ormander functional calculus: maximal and square function estimates [PDF]

open access: yes, 2015
We prove that the existence of a Mihlin-H\"ormander functional calculus for an operator $L$ implies the boundedness on $L^p$ of both the maximal operators and the continuous square functions build on spectral multipliers of $L.$ The considered multiplier

Schur multipliers of Cartan pairs

open access: yes, 2014
We define the Schur multipliers of a separable von Neumann algebra M with Cartan masa A, generalising the classical Schur multipliers of $B(\ell^2)$. We characterise these as the normal A-bimodule maps on M.

Economic Multipliers and Sectoral Linkages: Ghana and the New Oil Sector

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2016
The study seeks to assess the structure of the economy of Ghana in terms of changes in the economic structure before and after the production of oil in commercial quantities.

N-multipliers and their relations with n-homomorphisms

open access: yes, 2016
Let $A$ be a Banach algebra and $X$ be a Banach $A$-bimodule. We introduce and study the notions of $n$-multipliers and approximate local $n$-multipliers by generalizing the classical concept of multipliers from $A$ into $X$.

Transfer of Fourier multipliers into Schur multipliers and sumsets in a discrete group [PDF]

open access: yes, 2010
We inspect the relationship between relative Fourier multipliers on noncommutative Lebesgue-Orlicz spaces of a discrete group and relative Toeplitz-Schur multipliers on Schatten-von-Neumann-Orlicz classes.

Local Operator Multipliers and Positivity [PDF]

open access: yes, 2012
We establish an unbounded version of Stinespring's Theorem and a lifting result for Stinespring representations of completely positive modular maps defined on the space of all compact operators.

Quasi-multipliers of Hilbert and Banach C*-bimodules

open access: yes, 2010
Quasi-multipliers for a Hilbert C*-bimodule V were introduced by Brown, Mingo and Shen 1994 as a certain subset of the Banach bidual module V**. We give another (equivalent) definition of quasi-multipliers for Hilbert C*-bimodules using the centralizer ...
