Topological cyclic homology [PDF]

open access: yesHandbook of Homotopy Theory, 2019
This survey of topological cyclic homology is a chapter in the Handbook on Homotopy Theory. We give a brief introduction to topological cyclic homology and the cyclotomic trace map following Nikolaus-Scholze, followed by a proof of B\"okstedt periodicity

A convenient category of topological partial groups

open access: yesJournal of the Egyptian Mathematical Society, 2019
In this paper, the concept of ℘-continuous map is introduced and some of their basic properties are discussed. Also, the category Ḱ $\mathbf {K}\acute {}$, of topological partial groups, as objects and the ℘-morphisms of topological partial groups, as ...

Advances in the Theory of Compact Groups and Pro-Lie Groups in the Last Quarter Century

open access: yesAxioms, 2021
This article surveys the development of the theory of compact groups and pro-Lie groups, contextualizing the major achievements over 125 years and focusing on some progress in the last quarter century.

Free topological groups

open access: yesGeneral Topology and its Applications, 1974
AbstractMain Theorem. The free abelian topological group over a Tychonoff1 space contains as a closed subspace a homeomorphic copy of each finite power of the space.A major and immediate corollary of this theorem is: If P is a closed hereditary property of Tychonoff spaces, and if the free abelian topological group over a Tychonoff spaces has P, then ...

On monotonic bijections on subgroups of R

open access: yesApplied General Topology, 2016
We show that for any continuous monotonic  bijection $f$ on a $\sigma$-compact subgroup  $G\subset \mathbb R$ there exists a binary operation $+_f$ such that $\langle G, +_f\rangle$  is a topological group topologically isomorphic to $\langle G, +\rangle$

Topologically orderable groups

open access: bronzeGeneral Topology and its Applications, 1975
AbstractTopological groups whose topology can be induced by a total order are characterized up to homeomorphism. In particular, a non-metrizable topological group is in this class if and only if it has a totally ordered base at the identity consisting of (closed and) open subgroups.

Pseudo-Normality and Pseudo-Tychonoffness of Topological Groups

open access: yesMathematics
It is common knowledge that any topological group that satisfies the lowest separation axiom, T0, is immediately Hausdorff and completely regular; however, this is not the case for normality.

On transversal group topologies

open access: yesTopology and its Applications, 2005
AbstractTwo non-discrete Hausdorff group topologies τ1, τ2 on a group G are called transversal if the least upper bound τ1∨τ2 of τ1 and τ2 is the discrete topology. We show that an infinite totally bounded topological group never admits a transversal group topology and we obtain a new criterion for precompactness in lattice-theoretical terms (the ...

The equivalent condition of G-asymptotic tracking property and G-Lipschitz tracking property

open access: yesOpen Mathematics, 2022
In this paper, we introduce the concepts of GG-Lipschitz tracking property and GG-asymptotic tracking property in metric GG-space and obtain the equivalent conditions of GG-asymptotic tracking property in metric GG-space.
