The Chebyshev Set Problem in Riesz Space
Journal of Function Spaces, 2022 In this paper, we mainly study the best approximation theory in Riesz space, which is not constructed by the norm, but only rely on the order structure.

Novel Second-Order Accurate Implicit Numerical Methods for the Riesz Space Distributed-Order Advection-Dispersion Equations [PDF]
Advances in Mathematical Physics, 2015 We derive and analyze second-order accurate implicit numerical methods for the Riesz space distributed-order advection-dispersion equations (RSDO-ADE) in one-dimensional (1D) and two-dimensional (2D) cases, respectively.

The space of extended orthomorphisms in a Riesz space [PDF]
Pacific Journal of Mathematics, 1984 Some properties are discussed of the space \(Orth^{\infty}(L)\) of extended orthomorphisms on an Archimedean Riesz space L. An order bounded linear mapping \(\pi\) from an order dense ideal \(D\subseteq L\) into L is called an extended orthomorphism if \(\inf(| \pi f|,| g|)=0\) whenever \(f\in D\), \(g\in L\) and \(\inf(| f|,| g|)=0.\) The space \(Orth^

The Characterization and Stability of g-Riesz Frames for Super Hilbert Space
Journal of Function Spaces, 2015 G-frames and g-Riesz frames as generalized frames in Hilbert spaces have been studied by many authors in recent years. The super Hilbert space has a certain advantage compared with the Hilbert space in the field of studying quantum mechanics.

Riesz bases and positive operators on Hilbert space [PDF]
International Journal of Mathematics and Mathematical Sciences, 2003 It is shown that a normalized Riesz basis for a Hilbert space H (i.e., the isomorphic image of an orthonormal basis in H) induces in a natural way a new, but equivalent, inner product on H in which it is an orthonormal basis, thereby extending the sense ...

Karpatsʹkì Matematičnì Publìkacìï, 2021 We study measurable elements of a Riesz space $E$, i.e. elements $e \in E \setminus \{0\}$ for which the Boolean algebra $\mathfrak{F}_e$ of fragments of $e$ is measurable. In particular, we prove that the set $E_{\rm meas}$ of all measurable elements of

, 2021 The ergodic theorems of Hopf, Wiener and Birkhoff were extended to the context of Riesz spaces with a weak order unit and conditional expectation operator by Kuo, Labuschagne and Watson in [Ergodic Theory and the Strong Law of Large Numbers on Riesz Spaces. Journal of Mathematical Analysis and Applications, 325,(2007), 422-437.].

TEOREMA REPRESENTASI RIESZ–FRECHET PADA RUANG HILBERT
Barekeng, 2011 Hilbert space is a very important idea of the Davids Hilbert invention. In 1907, Riesz and Fréchet developed one of the theorem in Hilbert space called the Riesz-Fréchet representation theorem.
