Sobolev meets Riesz: a characterization of weighted Sobolev spaces via weighted Riesz bounded variation space

, 2023
We introduce weighted Riesz bounded variation spaces defined on an open subset of the $n$-dimensional Euclidean space and use them to characterize weighted Sobolev spaces when the weight belongs to the Muckenhoupt class. As an application, using Rubio de

The completion of a B-convex normed Riesz space is reflexive [PDF]

, 1973
If is a B-convex normed Riesz space, then the topological completion of is a closed subspace of ∗∗, the second Banach dual of . If N=∗∗ or N=∗∗x, then N is a B-convex σ-Dedekind complete normed Riesz space which is the Banach dual of a normed Riesz ...

High-Order Algorithms for Riesz Derivative and Their Applications (I)

Abstract and Applied Analysis, 2014
We firstly develop the high-order numerical algorithms for the left and right Riemann-Liouville derivatives. Using these derived schemes, we can get high-order algorithms for the Riesz fractional derivative.

The Riesz Space Structure of an Abelian W*-Algebra [PDF]

, 1969
Let M be an Abelian W*-algebra of operators on a Hilbert space H. Let M0 be the set of all linear, closed, densely defined transformations in H which commute with every unitary operator in the commutant M’ of M. A well known result of R.

Mixingales on Riesz spaces

Journal of Mathematical Analysis and Applications, 2013
A mixingale is a stochastic process which combines properties of martingales and mixing sequences. McLeish introduced the term mixingale at the $4^{th}$ Conference on Stochastic Processes and Application, at York University, Toronto, 1974, in the context of $L^2$.

ON FIRST AND SECOND PHI-VARIATION IN THE SENSE OF SCHRAMM-RIESZ // SOBRE LA PRIMERA Y SEGUNDA PHI-VARIACION EN EL SENTIDO DE SCHRAMM-RIESZ

Publicaciones en Ciencias y Tecnología, 2013
In this paper we present a generalization of the concepts of rst and second -variation (where is a certain sequence of positive convex function de ned on [0;+1)), in the sense of Schramm-Riesz for normed space valued functions de ned on an interval [a; b]

A characterization of Riesz spaces which are Riesz isomorphic to C(X) for some completely regular space X [PDF]

, 1989
Let E be an Archimedean Riesz space possessing a weak unit e and let Ω be the collection of all Riesz homomorphisms ø from E onto ℝ such that ø(e)=1. The Gelfand mapping G :x→x^ on E is defined by x^(ø) = ø(x) for all ø∈Ω.

Finite Difference and Chebyshev Collocation for Time-Fractional and Riesz Space Distributed-Order Advection–Diffusion Equation with Time-Delay

Fractal and Fractional
In this paper, we have established a numerical method for a class of time-fractional and Riesz space distributed-order advection–diffusion equation with time-delay.

An Extension of the Concept of the Order Dual of a Riesz Space

, 1967
Let L be a σ-Dedekind complete Riesz space. In (8), H. Nakano uses an extension of the multiplication operator on a Riesz space into itself (analagous to the closed operator on a Hilbert space) to obtain a representation space for the Riesz space L.
