Inequalities in Lp−1 for the extended Lp best approximation operator
(Elsevier Inc, 2012-09)
The best polynomial approximation operator was recently extended by one of the authors from Lp to Lp−1. In this paper, we study weak and strong inequalities for maximal operators related with the extended best polynomial ...
An the new riemann liouville fractional operator extended
(JS Publication, 2017)
In this paper we will introduce a new and modi ed Riemann-Liouville fractional operator that resulted from modifying the
extended fractional derivative due to M. Ozarslan. We will study some familiar functions regarding ...
A characterization of the extended best φ-approximation operator
(Taylor & Francis, 2011-05)
Given an non necessarily linear operator T defined from an Orlicz space L φ′(Ω, , μ) into itself, where φ′ denote the derivative of a strictly convex function φ, we give necessary and sufficient conditions on T assuring ...
Ordered phases in the extended Hubbard model
(Elsevier B.V., 1994-04-02)
A novel method to probe the diverse phases for the extended Hubbard model (EHM), including the correlated hopping term, is presented. We extend an effective medium approach [1] to a bipartite lattice, allowing for charge- ...
Extended best polynomial approximation operator in Orlicz Spaces
(Taylor & Francis, 2015-04)
In this article we consider the best polynomial approximation operator, defined in an Orlicz space L Φ(B), and its extension to L ϕ(B) where ϕ is the derivative function of Φ. A characterization of these operators and ...
Inequalities for the Extended Best Polynomial Approximation Operator in Orlicz Spaces
(Springer Heidelberg, 2019-02)
In this paper we pursue the study of the best approximation operator extended from L^Φ to L^φ, where φ denotes the derivative of the function Φ. We get pointwise convergence for the coefficients of the extended best ...
Transfer matrices for discrete Hermitian operators and absolutely continuous spectrum
(Academic Press Inc., 2021)
© 2021 Elsevier Inc.We introduce a transfer matrix method for the spectral analysis of discrete Hermitian operators with locally finite hopping. Such operators can be associated with a locally finite graph structure and ...
Diagonal extendible multilinear operators between Lp-spaces
(Real Acad Ciencias Exactas Fisicas & Naturales, 2014-09)
We study extendibility of diagonal multilinear operators from Lp to Lq spaces. We determine the values of p and q for which every diagonal n-linear operator is extendible, and those for which the only extendible ones are ...
