Products of a Compact Space and a Metric Space [PDF]

open access: yesProceedings of the American Mathematical Society, 1987
Let X × Y X \times Y be the product of a compact space X X and a metric space Y Y . We consider a continuous closed image Z Z of X × Y X \times Y . Moreover, we consider a closed subspace R R in

In‐Situ Growth of 2D MOFs as a Molecular Sieving Layer on SnS2 Nanoflakes for Realizing Ultraselective H2S Detection

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
The ultraselective H2S detection of the ZIF‐L/SnS2 heterostructure is demonstrated. The introduction of 2‐dimensional (2D) breathable ZIF‐L results in a substantial increase in H2S selectivity attributable to the molecular sieving effect, which impedes the permeation of gases with large kinetic diameters and high polarity.

Some properties of b-weakly compact operators on Banach lattices

open access: yesپژوهش‌های ریاضی, 2021
In this paper we give some necessary and sufficient conditions for which each Banach lattice  is    space and we study some properties of b-weakly compact operators from a Banach lattice  into a Banach space .

Slice Theorem For Differential Spaces And Reduction By Stages

open access: yesDemonstratio Mathematica, 2014
We show that the space P/G of orbits of a proper action of a Lie group G on a locally compact differential space P is a locally compact differential space with quotient topology.

Compact spaces and products of finite spaces [PDF]

open access: yesProceedings of the American Mathematical Society, 1972
It is shown that the compact spaces are precisely the extension closed subspaces of products of finite spaces, where a subspace is extension closed if every open cover of the subspace extends to an open cover of the entire space. Every closed subspace is extension closed, and for Hausdorff spaces the converse also holds.

Internal Temperature Evolution Metrology and Analytics in Li‐Ion Cells

open access: yesAdvanced Functional Materials, EarlyView.
This study investigates the non‐linear evolution of internal temperatures across diverse operating conditions, highlighting the disparities between internal and external measurements and the resulting thermal asymmetries. The coupled thermo‐electrochemical modeling framework provides a comprehensive analysis of various heat generation modes, examining ...

On the Krein-Milman-Ky Fan theorem for convex compact metrizable sets

open access: yes, 2016
The Krein-Milman theorem (1940) states that every convex compact subset of a Hausdorfflocally convex topological space, is the closed convex hull of its extreme points.
