Extended Fuzzy Metrics and Fixed Point Theorems
Mathematics, 2019 In this paper, we study those fuzzy metrics M on X, in the George and Veeramani’s sense, such that ⋀ t > 0 M ( x , y , t ) > 0 . The continuous extension M 0 of M to X 2 × 0 , + ∞ is called extended

Wave‐Partition‐Governed Dual‐Site Spallation in Single Crystals
Advanced Science, EarlyView.Crystalline anisotropy shapes shock‐wave propagation and the resulting damage evolution in single crystals. Large‐scale molecular dynamics and damage modeling uncover a dual‐spallation mechanism driven by anisotropic elasticplastic wave separation, which mitigates damage accumulation.

Fixed Point Theorems for Asymptotically Contractive Multimappings
International Journal of Mathematics and Mathematical Sciences, 2012 We present fixed point theorems for a nonexpansive set-valued mapping from a closed convex subset of a reflexive Banach space into itself under some asymptotic contraction assumptions.

Imperfection in Semiconductors Leading to High Performance Devices
Advanced Science, EarlyView.Crystalline perfection is typically pursued in semiconductors to enhance device performance. However, through modeling and experimental work, we show that defects can be strategically employed in a specific detection regime to increase sensitivity to extreme values. GaN diodes are demonstrated to effectively detect high‐energy proton beams at fluxes as

Some Fixed Point Theorems in G-metric Spaces
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2012 We prove some fixed point theorems for self mappings satisfying some kind of contractive type conditions on complete G-metric ...

A Perspective on Interactive Theorem Provers in Physics
Advanced Science, EarlyView.Into an interactive theorem provers (ITPs), one can write mathematical definitions, theorems and proofs, and the correctness of those results is automatically checked. This perspective goes over the best usage of ITPs within physics and motivates the open‐source community run project PhysLean, the aim of which is to be a library for digitalized physics

Fixed point theorems via Nash Equilibria [PDF]
In this note we show that the fixed points of a continuous function (or of an upper semi-continuous correspondence, with non-empty and convex values) can be attained as Nash Equilibria of a game with finitely many players.
