Wall–chamber decompositions for generalised Monge–Ampère equations

open access: yesJournal of the London Mathematical Society, Volume 114, Issue 1, July 2026.
Abstract Generalised Monge–Ampère (gMA) equations form a large class of PDE including Donaldson's J‐equation, inverse Hessian equations, some supercritical deformed Hermitian–Yang–Mills (dHYM) equations and some Z‐critical equations. Solvability of these equations is characterised by numerical criteria involving intersection numbers over all ...

Time‐Resolved SNOM via Phase‐Domain Sampling

open access: yesNanophotonics, Volume 15, Issue 12, 25 June 2026.
Time‐resolved scanning near‐field optical microscopy (tr‐SNOM) grants access to the dynamic dielectric function of monolayer and multilayer WS2, using visible wavelengths. In order to use a femtosecond laser with a repetition rate of 200 kHz, the signal is sampled and demodulated in the modulation phase domain, marking the first realization of tr‐SNOM ...

Seniority‐Zero Quadratic Canonical Transformation Theory

open access: yesInternational Journal of Quantum Chemistry, Volume 126, Issue 12, June 15, 2026.
We construct a unitary transformation of electronic Hamiltonians using quadratic canonical transformation theory, choosing the transformation to minimize the non‐seniority‐zero elements of the transformed Hamiltonian. This allows us to add dynamic correlation to the static correlation inherent in orbital‐optimized doubly‐occupied (seniority‐zero ...

A (CHR)3-flat trans-Sasakian manifold

open access: yesPracì Mìžnarodnogo Geometričnogo Centru, 2019
In [4] M. Prvanovic considered several curvaturelike tensors defined for Hermitian manifolds. Developing her ideas in [3], we defined in an almost contact Riemannian manifold another new curvaturelike tensor field, which is called a contact ...

Single‐Photon Emission From TMDCs through Strong Coupling to EQ Plasmon Modes of an Au Metasurface

open access: yesNanophotonics, Volume 15, Issue 11, 13 June 2026.
Compact, deterministic solid‐state single‐photon sources that operate at room temperature and integrate with planar nanophotonics are essential for the development of scalable quantum photonic technologies. This work presents a TMDC monolayer strongly coupled to a gold (Au) metasurface featuring an electric quadrupole mode, enabling high‐purity single ...

Riemannian submersions From Almost Hermitian Manifolds [PDF]

open access: yesTaiwanese Journal of Mathematics, 2013
We survey main results of holomorphic submersions, anti-invariant submersions, slant submersions, semi-invariant submersions and semi-slant submersions defined on almost Hermitian manifolds. We also give an application of Riemannian submersions on redundant robotic chains obtained by Altafini and propose some open problems related to topics discussed ...

Inverse Design of Mirror‐Symmetric Disordered Systems for Broadband Perfect Transmission

open access: yesLaser &Photonics Reviews, Volume 20, Issue 11, 5 June 2026.
This work introduces an inverse design approach to achieve broadband perfect wave transmission in mirror‐symmetric disordered media. Leveraging symmetry simplifies optimization and enables control of multiple reflectionless states. Experiments in microwave waveguides confirm the design of exceptional points, bandpass filters, and broadband quasi ...

Invariant almost Hermitian structures on flag manifolds

open access: yesAdvances in Mathematics, 2003
Let \(\mathfrak g\) be a complex semi-simple Lie algebra of a complex Lie group \(G\), and let \(\mathbb{F}=G/P\) be a maximal flag manifold of \(G\), where \(P\) is a minimal parabolic (Borel) subgroup. For any maximal compact subgroup \(U\) of \(G\) the manifold \(\mathbb{F}\) can be written as \(\mathbb{F}=U/T\), where \(T\subset U\) is a maximal ...

Conformal Riemannian maps from almost Hermitian manifolds

open access: yesTurkish Journal of Mathematics, 2018
Conformal Riemannian maps from almost Hermitian manifolds to Riemannian manifolds, namely conformal invariant Riemannian maps, holomorphic conformal Riemannian maps, and conformal antiinvariant Riemannian maps, are introduced.

Existence of Generalized Maxwell–Einstein Metrics on Completions of Certain Line Bundles

open access: yesMathematics
In Kähler geometry, Calabi extremal metrics serves as a class of more available special metrics than Kähler metrics with constant scalar curvatures, as a generalization of Kähler Einstein metrics. In recent years, Maxwell–Einstein metrics (or conformally
