Unitary representability of free abelian topological groups

open access: yesApplied General Topology, 2008
For every Tikhonov space X the free abelian topological group A(X) and the free locally convex vector space L(X) admit a topologically faithful unitary representation. For compact spaces X this is due to Jorge Galindo.

Architecture‐Driven Functional Coupling in Vertically Aligned Nanocomposites

open access: yesAdvanced Functional Materials, EarlyView.
Vertically aligned nanocomposites define a growth‐engineered architecture in which vertical interfaces, strain fields, defect pathways, and phase connectivity are created simultaneously. This review shows how these architectural features couple ferroic, optical, ionic, electrochemical, and device responses, establishing design rules and open challenges

Locally compact $F$-spaces, sub-stonean spaces and quotients of locally compact groups.

open access: yesMATHEMATICA SCANDINAVICA, 1991
The author defines an \(F'\)-space to be a completely regular space in which disjoint open \(F_ \sigma\)-sets have disjoint closures. He then presents five characterizations of locally compact Hausdorff spaces that are \(F'\)-spaces, and subsequently proves that if \(G\) is a locally compact group and \(H\) is a closed subgroup for which the quotient ...

Metrizability of Locally Compact Vector Spaces [PDF]

open access: yesProceedings of the American Mathematical Society, 1971
By use of the theory of characters and the Pontryagin-van Kampen theorem, it is shown that if E E is a locally compact ...

The Concentration Function Problem for Locally Compact Groups Revisited: Nondissipating Space-Time Random Walks, -Decomposable Laws, and Their Continuous Time Analogues

open access: yesJournal of Mathematics, 2013
The concentration function problem for locally compact groups is concerned with the structure of groups admitting adapted nondissipating random walks.

Covalent Functionalization of 2D Semiconductors: A Roadmap to Advanced Electronic Devices

open access: yesAdvanced Functional Materials, EarlyView.
This Review presents recent advances in the covalent functionalization strategies for two‐dimensional semiconductors and their implementation in modern technologies. Layered materials are modified through diverse molecular chemistries (e.g., thiols, diazonium salts, alkyl halides, and electron‐deficient species) to tailor their surface properties ...

On uniformly locally compact quasi-uniform hyperspaces [PDF]

open access: yes, 2004
summary:We characterize those Tychonoff quasi-uniform spaces $(X,\mathcal {U})$ for which the Hausdorff-Bourbaki quasi-uniformity is uniformly locally compact on the family $\mathcal {K}_{0}(X)$ of nonempty compact subsets of $X$. We deduce, among other

Condition for a function space to be locally compact [PDF]

open access: yesProceedings of the American Mathematical Society, 1972
Let F be an equicontinuous family of functions from a compact Hausdorff space to a locally compact Hausdorff uniform space. In this paper we prove that the pointwise closure of F is locally compact relative to the topology of uniform con-

On cofree S-spaces and cofree S-flows

open access: yesApplied General Topology, 2012
Let S-Tych be the category of Tychonoff S-spaces for a topological monoid S. We study the cofree S-spaces and cofree S-flows over topological spaces and we prove that for any topological space X and a topological monoid S, the function space C(S,X) with ...
