Convergence properties of dynamic mode decomposition for analytic interval maps

open access: yesCommunications on Pure and Applied Mathematics, Volume 79, Issue 2, Page 179-206, February 2026.
Abstract Extended dynamic mode decomposition (EDMD) is a data‐driven algorithm for approximating spectral data of the Koopman operator associated to a dynamical system, combining a Galerkin method with N$N$ functions and a quadrature method with M$M$ quadrature nodes.

Empirical Investigation of the Riemann Hypothesis Using Machine Learning: A Falsifiability-Oriented Approach

open access: yesMathematics
The Riemann Hypothesis (RH) asserts that all non-trivial zeros of the Riemann zeta function lie on the critical line Re(s) = 0.5, yet no general proof exists despite extensive numerical verification.

Mesh, Hydrodynamic Boundary, and Uncertainty Analysis of the 2D‐SWEs: Taking Numerical Simulation of River Networks as an Example

open access: yesWater Resources Research, Volume 62, Issue 2, February 2026.
Abstract Targeting the issues of insufficient predictive ability and inefficient computation in two‐dimensional shallow water equations (2D‐SWEs), this study deeply couples the mesh and hydrodynamic boundary, constructing multiple 2D hydrodynamic models (run 2,640 times).

Riemann hypothesis or Riemann theory

open access: yes, 2018
the Riemann hypothesis states that any zero of the Riemann zeta function other than the trivial zeros has a real part equals half ”, this paper has only 7 pages, no figures, no charts, and contains a somehow peculiar proof to the Riemann hypothesis, which Sir David Hilbert once said about,” if I were to awaken after having slept for a thousand years ...

Coordinate‐ and Spacetime‐Independent Quantum Physics

open access: yesAnnalen der Physik, Volume 538, Issue 1, January 2026.
This article studies in the framework of quantum field theory in curved spacetime, if there exists a single zero‐rank‐tensor solution of a Klein‐Gordon PDE, being valid at once for the depicted spacetimes. The answer is shown to be affirmative, even for a class of such solutions having the standard applications in particle physics. ABSTRACT The concept

Riemann hypothesis to Riemann theory

open access: yes, 2018
the Riemann hypothesis states that any zero of the Riemann zeta function other than the trivial zeros has a real part equals half ”, this paper has only 7 pages, no figures, no charts, and contains a somehow distinct proof to the Riemann hypothesis, which Sir David Hilbert once said about,” if I were to awaken after having slept for a thousand years ...

Interval‐valued Caputo–Fabrizio fractional derivative in continuous programming

open access: yesAsian Journal of Control, Volume 28, Issue 1, Page 497-514, January 2026.
Abstract This study investigates a novel class of variational programming problems characterized by fractional interval values, formulated under the Caputo–Fabrizio fractional derivative with an exponential kernel. Invex and generalized invex functions are used to discuss the Mond–Weir‐type dual problem for the considered variational problem.

Fractional Kinetic Modelling of the Adsorption and Desorption Processes From Experimental SPR Curves

open access: yesJournal of Chemometrics, Volume 40, Issue 1, January 2026.
ABSTRACT The application of surface plasmon resonance (SPR) has transformed the study of interactions between a ligand immobilized on the surface of a sensor chip (LS$$ {L}_S $$) and an analyte in solution (A$$ A $$). This technique enables the real‐time monitoring of binding processes with high sensitivity. The adsorption–desorption dynamics, A+LS→ALS$
