Some algebraic properties of Lambert Multipliers on $L^2$ spaces
In this paper, we determine the structure of the space of multipliers of the range of a composition operator $C_varphi$ that induces by the conditional expectation between two $L^p(Sigma)$ spaces.
متن کاملSome topologies on the space of quasi-multipliers
Assume that $A$ is a Banach algebra. We define the $beta-$topology and the $gamma-$topology on the space $QM_{el}(A^{*})$ of all bounded extended left quasi-multipliers of $A^{*}.$ We establish further properties of $(QM_{el}(A^{*}),gamma)$ when $A$ is a $C^{*}-$algebra. In particular, we characterize the $gamma-$dual of $QM_{el}(A^{*})$ and prove that $(QM_{el}(A^{*}),gamma)^{*},$...
متن کاملMultipliers on a Hilbert Space of Functions on R
For a Hilbert space H ⊂ L loc (R) of functions on R we obtain a representation theorem for the multipliers M commuting with the shift operator S. This generalizes the classical result for multipliers in L(R) as well as our previous result for multipliers in weighted space L ω (R). Moreover, we obtain a description of the spectrum of S.
متن کاملComparative Analysis of Sectoral Multipliers of Input-Output Model and Social Accounting Matrix
The present study is to indicate that the comparison between sectoral production multipliers of an input-output (I/O) model and a social accounting matrix (SAM) framework is almost impossible without taking into account accounting balances and theoretical considerations. Theoretically, the I/O model provides the Leontief’s production function, on the basis of which sectoral output multiplier ca...
متن کاملMULTIPLIERS AND THEIR APPLICATIONS IN EARTHQUAKE ENGINEERING
In this paper we shall study the multipliers on Banach algebras and We prove some results concerning Arens regularity and amenability of the Banach algebra M(A) of all multipliers on a given Banach algebra A. We also show that, under special hypotheses, each Jordan multiplier on a Banach algebra without order is a multiplier. Finally, we present some applications of m...
