Next Generation of Thermal Barrier Coatings with High Temperature Metal‐Silicide Metamaterials

Advanced Optical Materials, EarlyView.
Thermal metamaterials have emerged as a powerful platform in the engineering of radiative heat transfer across a broad range of applications, including thermal imaging, passive cooling, and thermo‐photovoltaics. Here, a novel application is presented for metamaterials: thermal dual barrier coatings (TDBCs).

Nadler’s fixed point theorem in ν-generalized metric spaces

Fixed Point Theory and Applications, 2017
We extend Nadler’s fixed point theorem to ν-generalized metric spaces. Through the proof of the above extension, we understand more deeply the mathematical structure of a ν-generalized metric space.

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.

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.

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.

Fixed point theorem utilizing operators and functionals

Electronic Journal of Qualitative Theory of Differential Equations, 2012
This paper presents a fixed point theorem utilizing operators and functionals in the spirit of the original Leggett-Williams fixed point theorem which is void of any invariance-like conditions.

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.

Numerical and Experimental Methods for Estimating the Propagation Loss in Microphotonic Waveguides

Advanced Photonics Research, EarlyView.
Finite‐element finite‐difference time domain, eigenmode‐expansion, and volume‐current simulations are benchmarked against cut‐back, ring‐resonator, and OFDR measurements to quantify waveguide propagation loss in integrated photonic circuits. Scattering, absorption, leakage, and back‐reflection contributions are dissected; error sources are ranked; and ...

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 ...
