Cofinal bicompleteness and quasi-metrizability [PDF]

, 1999
[EN] We introduce the notions of a cofinally bicomplete quasi-uniformity and of a cofinally bicomplete quasi-pseudometric. The Sorgenfrey quasi-metric and the Kofner quasi-metric are interesting examples of cofinally bicomplete quasi-metrics.

Bayesian games with nested information

Theoretical Economics, Volume 21, Issue 1, Page 204-240, January 2026.
A Bayesian game is said to have nested information if the players are ordered and each player knows the types of all players that follow her in that order. We prove that all multiplayer Bayesian games with finite action spaces, bounded payoffs, Polish type spaces, and nested information admit a Bayesian equilibrium.

Completely metrizable spaces of embeddings

, 1982
A study is made of the complete metrizability of spaces of embeddings and spaces of homeomorphisms under the compact-open topology. It is shown that the space of continuous injections from a hemicompact metric space into a complete metric space is ...

Compact metrizable groups are isometry groups of compact metric spaces [PDF]

Proceedings of the American Mathematical Society, 2007
This note is devoted to proving the following result: given a compact metrizable group G, there is a compact metric space K such that G is isomorphic (as a topological group) to the isometry group of K.

Dual spaces of geodesic currents

Journal of Topology, Volume 18, Issue 4, December 2025.
Abstract Every geodesic current on a hyperbolic surface has an associated dual space. If the current is a lamination, this dual embeds isometrically into a real tree. We show that, in general, the dual space is a Gromov hyperbolic metric tree‐graded space, and express its Gromov hyperbolicity constant in terms of the geodesic current.

Locally arcwise connected metrizable spaces with the fixed point property are complete-metrizable

, 2006
Metrizable spaces which have no closed subset homeomorphic to the real halfline are considered. Complete-metrizability of such locally arcwise connected spaces is proved (Corollary 4) and a simple formula for a complete metric is given in Theorem ...

ℐ-sn-metrizable spaces and the images of semi-metric spaces

Open Mathematics
Abstract The theory of generalized metric spaces is an active topic in general topology. In this article, we utilize the concepts of ideal convergence and networks to discuss the metrization problem and the mutual classification problem between spaces and mappings in topological spaces. We define

Konform geometria Riemann-Finsler típusú metrikus tereken = Conform geometry of spaces with Riemann-Finsler metrics

, 2010
Témánk az ún. Finsler-terek konform geometriája, különös tekintettel speciális tértípusok konform ekvivalenciájára. Egy sokaság Finsler-tér, ha az érintővektorok hosszát egy nem feltétlenül belső szorzatból származó funkcionálsereg segítségével mérni ...
