The equivariant Lefschetz fixed point theorem for proper cocompact G-manifolds
, 2001 Suppose one is given a discrete group G, a cocompact proper G-manifold M, and a G-self-map f of M. Then we introduce the equivariant Lefschetz class of f, which is globally defined in terms of cellular chain complexes, and the local equivariant Lefschetz

Optical Poling of Ferroelectric Liquids
Advanced Optical Materials, EarlyView.The optical control of size and shape of polar domains in ferroelectric nematic liquid crystal cells is reported. In sufficiently thin samples, light irradiation induces the formation of a novel singular spiral‐shape arrangement of the polar director as a response to localized illumination.

A fixed point theorem for distributions
Stochastic Processes and their Applications, 1992 The author studies, in a systematic form, the contractive behavior of the map \(S\) of distributions to distributions \(S(F)\overset{\mathcal D}=\sum_ i T_ i X_ i+C\), \((C,T=(T_ 1,T_ 2,\dots))\), \(X_ i\) are independent random variables with distribution function \(F\). Further the author obtains the higher and exponential moments of the fixed point.

Coherent Control of Thermal Radiation with Nanophotonics
Advanced Photonics Research, EarlyView.This review explores the innovative control of thermal radiation coherence using nanophotonic structures. The fundamentals of thermal radiation, coherence control strategies (temporal, spatial, and polarization), and their applications in infrared sensing, radiative cooling, thermal camouflage, and imaging, are discussed.

A Generalization of Kannan's Fixed Point Theorem
Fixed Point Theory and Applications, 2009 In order to observe the condition of Kannan mappings, we prove a generalization of Kannan's fixed point theorem. Our theorem involves constants and we obtain the best constants to ensure a fixed point.

Nonlinear Inequality, Fixed Point and NashEquilibrium [PDF]
In this paper, we give new sufficient conditions for the existence of a solution of theg-maximum equality. As a consequence, we prove a new fixed point theorem.

Incoherent Digital Holography Empowered by Wavefront and Information Engineering: A Review
Advanced Photonics Research, EarlyView.Advancements in incoherent digital holography (IDH) have been achieved via wavefront engineering (using spatial light modulators, diffractive optics, and metasurfaces) and information engineering (using compressive sensing and deep learning). This paper presents an overview of IDH with wavefront and information engineering, paving the way toward its ...

Existence of Perfect Equilibria: A Direct Proof [PDF]
We formulate and prove a modification of Eilenberg-Montgomery fixed-point theorem, which is a generalization of Kakutani’s theorem. It enables us to provide a direct proof of the existence of perfect equilibria in finite normal form games and extensive ...

Non‐Hermitian Topological Lattice Photonics: An Analytic Perspective
Advanced Photonics Research, EarlyView.This review establishes exact analytical solutions for non‐Hermitian Hatano–Nelson, Su–Schrieffer–Heeger, and generalized Rice–Mele models. We demonstrate non‐Hermitian skin effects via point‐gap topology, hybrid skin‐topological edge states in 2D lattices, and spin‐polarized boundary modes governed by dual bulk‐boundary correspondence.
