Joint discrete Approximation of analytic Functions by shifts of Lerch zeta-Functions

Mathematical Modelling and Analysis
The Lerch zeta-function $L(\lambda, \alpha,s)$, $s=\sigma+it$, depends on two real parameters $\lambda$ and $01$, is defined by the Dirichlet series $\sum_{m=0}^\infty \ee^{2\pi i\lambda m} (m+\alpha)^{-s}$, and by analytic continuation elsewhere. In the

A discrete Version of the Mishou Theorem Related to periodic zeta-Functions

Mathematical Modelling and Analysis
In the paper, we consider simultaneous approximation of a pair of analytic functions by discrete shifts $\zeta_{u_N}(s+ikh_1; \ga)$ and $\zeta_{u_N}(s+ikh_2, \alpha; \gb)$ of the absolutely convergent Dirichlet series connected to the periodic zeta ...

Global weak solutions for the compressible Poisson–Nernst–Planck–Navier–Stokes system

Journal of the London Mathematical Society, Volume 113, Issue 5, May 2026.
Abstract We consider the compressible Poisson–Nernst–Planck–Navier–Stokes (PNPNS) system of equations, governing the transport of charged particles under the influence of the self‐consistent electrostatic potential, in a three‐dimensional bounded domain.

Counting 5‐isogenies of elliptic curves over Q$\mathbb {Q}$

Journal of the London Mathematical Society, Volume 113, Issue 5, May 2026.
Abstract We show that the number of 5‐isogenies of elliptic curves defined over Q$\mathbb {Q}$ with naive height bounded by H>0$H > 0$ is asymptotic to C5·H1/6(logH)2$C_5\cdot H^{1/6} (\log H)^2$ for some explicitly computable constant C5>0$C_5 > 0$. This settles the asymptotic count of rational points on the genus zero modular curves X0(m)$\mathcal {X}

Multiple Time‐Scale Homogenization of Coupled Corrosion‐Fatigue in Structural Concrete

International Journal for Numerical Methods in Engineering, Volume 127, Issue 7, 15 April 2026.
ABSTRACT Reinforced concrete structures exposed to chloride‐rich environments and cyclic mechanical loading experience simultaneous corrosion of steel reinforcement and fatigue‐induced concrete cracking, leading to complex, nonlinear degradation that cannot be accurately captured by conventional sequential analyses.

Elucidating the Physical and Mathematical Properties of the Prouhet‐Thue‐Morse Sequence in Quantum Computing

Annalen der Physik, Volume 538, Issue 4, April 2026.
The Prouhet‐Thue‐Morse (PTM) sequence emerges as a unifying thread across quantum error correction, noise‐resistant memories, spin‐chain dynamics, quantum chaos, and Dirichlet links to the Riemann zeta function. Mapping PTM‐encoded logical states onto qubit and qudit architectures uncovers symmetry‐protected resilience and multifractal signatures ...

The Generalized Riemann Hypothesis and Applications to Primality Testing

, 2021
The Riemann Hypothesis, posed in 1859 by Bernhard Riemann, is about zerosof the Riemann zeta-function in the complex plane. The zeta-function can be repre-sented as a sum over positive integers n of terms 1/ns when s is a complex numberwith real part ...

Application of High‐Order Direct Flux Reconstruction and Stiffness‐Resilient Time Integration to Simulations of Idealized Atmospheric Flows

International Journal for Numerical Methods in Fluids, Volume 98, Issue 4, Page 448-468, April 2026.
The proposed work implements a direct flux reconstruction method for spatial discretization and a stiffness‐resilient exponential time integration method for temporal discretization on the cube‐sphere grid. A space‐time tensor formalism is employed to provide a general representation in any curvilinear coordinate system. This combination enables highly
