X‐ray waveguide optics at GINIX/P10 PETRA III: recent progress and future directions
Journal of Synchrotron Radiation, Volume 33, Issue 2, Page 298-313, March 2026.X‐ray waveguide optics enable spatial and coherence filtering of a nano‐focused synchrotron beam and provide tailored illumination wavefronts for holographic imaging. Progress in fabrication, characterization and advanced waveguide interferometers can enhance holographic imaging.Here we report on recent progress in X‐ray waveguide optics for full‐field

Journal of Ecology, Volume 114, Issue 3, March 2026.Host‐tree identity, particularly bark physico‐chemical traits, emerged as the dominant driver of epiphytic lichen and bryophyte community composition in this closed‐canopy temperate forest system, while microclimate plays a subordinate role. Spatial structure and proximity contributed additional effects for both groups, but for lichens, habitat ...

On quantum ergodicity for higher‐dimensional cat maps modulo prime powers
Bulletin of the London Mathematical Society, Volume 58, Issue 3, March 2026.Abstract A discrete model of quantum ergodicity of linear maps generated by symplectic matrices A∈Sp(2d,Z)$A \in \operatorname{Sp}(2d,{\mathbb {Z}})$ modulo an integer N⩾1$N\geqslant 1$, has been studied for d=1$d=1$ and almost all N$N$ by Kurlberg and Rudnick (2001, Comm. Math. Phys., 222, 201–227).

Karpatsʹkì Matematičnì Publìkacìï, 2018 We study a problem with periodic boundary conditions for a $2n$-order differential equation whose coefficients are non-self-adjoint operators. It is established that the operator of the problem has two invariant subspaces generated by the involution ...

Brownian Motion With Partial Resetting Conditioned to Stay Positive
Bulletin of the London Mathematical Society, Volume 58, Issue 3, March 2026.Abstract We consider Brownian motion with partial resetting, which has recently attracted a lot of attention in physics as well as the mathematics literature. We analyze the speed of convergence of this process towards stationarity as well as its quasistationary behavior.

NUMERICAL METHODS FOR DISCONTINUOUS STURM-LIOUVILLE PROBLEMS
Journal of New Theory, 2015 − This study is devoted to determining the eigenvalues and eigenfunctions of a discontinuous Sturm-Liouville Problem. By modifying the finite difference method, we have developed anumerical approximation to the eigenvalues and ...

Scattering theory for difference equations with operator coefficients
Journal of the London Mathematical Society, Volume 113, Issue 3, March 2026.Abstract We investigate a class of second‐order difference equations featuring operator‐valued coefficients with the aim of approaching problems of stationary scattering theory. We focus on various compact perturbations of the discrete Laplacian given in a Hilbert space of bi‐infinite square‐summable sequences with entries from a fixed Hilbert space ...

Biorthogonality condition for axisymmetric stokes flow in spherical geometries
International Journal of Mathematics and Mathematical Sciences, 2000 We derive the biorthogonality condition for axisymmetric Stokes flow in a region between two concentric spheres. This biorthogonality condition is a property satisfied by the eigenfunctions and adjoint eigenfunctions, which is needed to compute the ...

Liouville properties for differential inequalities with (p,q)$(p,q)$ Laplacian operator
Journal of the London Mathematical Society, Volume 113, Issue 3, March 2026.Abstract In this paper, we establish several Liouville‐type theorems for a class of nonhomogenenous quasilinear inequalities. In the first part, we prove various Liouville results associated with nonnegative solutions to Ps$P_s$ −Δpu−Δqu⩾us−1inΩ,$$\begin{equation} -\Delta _p u-\Delta _q u\geqslant u^{s-1} \, \text{ in }\, \Omega, \end{equation}$$where ...
