Completely positive maps on modules, instruments, extremality problems, and applications to physics

, 2012
Convex sets of completely positive maps and positive semidefinite kernels are considered in the most general context of modules over $C^*$-algebras and a complete charaterization of their extreme points is obtained.

Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions

Advanced Functional Materials, EarlyView.
DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries

Some Novel Fixed-Point Results in Neutrosophic Soft Metric Space With Application in Decision-Making to Select the Optimal Adsorbent

Journal of Mathematics
In this research paper, the concepts of compatible maps and maps of type α¯ and (β¯) within the framework of neutrosophic soft metric spaces (NSMS) are established. The interconnections between α¯- and (β¯)-type maps are also clarified. Additionally, the

Cone Metric Spaces over Topological Modules and Fixed Point Theorems for Lipschitz Mappings

Mathematics, 2020
In this paper, we introduce the concept of cone metric space over a topological left module and we establish some coincidence and common fixed point theorems for self-mappings satisfying a condition of Lipschitz type.

A local fluctuation theorem

, 1998
A mechanism for the validity of a local version of the fluctuation theorem, uniform in the system size, is discussed for a reversible chain of weakly coupled Anosov systems.Comment: plain TeX, 1 ...

Biodegradable and Recyclable Luminescent Mixed‐Matrix‐Membranes, Hydrogels, and Cryogels based on Nanoscale Metal‐Organic Frameworks and Biopolymers

Advanced Functional Materials, EarlyView.
The study presents biodegradable and recyclable mixed‐matrix membranes (MMMs), hydrogels, and cryogels using luminescent nanoscale metal‐organic frameworks (nMOFs) and biopolymers. These bio‐nMOF‐MMMs combine europium‐based nMOFs as probes for the status of the materials with the biopolymers agar and gelatine and present alternatives to conventional ...

A common fixed point theorem for weakly compatible multi-valued mappings satisfying strongly tangential property [PDF]

Mathematica Moravica, 2014
In this paper we prove a common fixed point theorem for two weakly compatible pairs of single and set-valued mappings which satisfying contractive condition of integral type in metric space by using the concept of strongly tangential property, our ...

On arithmetic families of filtered phi-modules and crystalline representations [PDF]

, 2011
We consider stacks of filtered phi-modules over rigid analytic spaces and adic spaces. We show that these modules parametrize p-adic Galois representations of the absolute Galois group of a p-adic field with varying coefficients over an open substack ...

The topological cyclic Deligne conjecture

, 2009
Let O be a cyclic topological operad with multiplication. In the framework of the cosimplicial machinery by McClure and Smith, we prove that the totalization of the cosimplicial space associated to O has an action of an operad equivalent to the framed ...

Common fixed point theorems for weakly compatible hybrid mappings

Journal of King Saud University - Science, 2011
AbstractThe purpose of this paper is to study common fixed point theorems for set-valued and single-valued mappings in fuzzy metric and fuzzy 2-metric spaces. Also, we give an example to support our theorem. Generalizations and extensions of known results are thereby obtained. In particular, theorems by Pathak and Singh (2007), Sharma and Tiwari (2005)
