Colimits in the category Seg of Segal topological algebras [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2022
In this paper we find sufficient conditions for a direct system of Segal topological algebras to have a colimit in the category Seg of Segal topological algebras.

Products and coproducts in the category S(B) of Segal topological algebras; pp. 89–99 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2019
Let B be a topological algebra and S(B) the category of Segal topological algebras. In the present paper we show that all coproducts of two objects of the category S(B) always exist.

Some remarks on the Gelfand–Naimark–Segal representations of topological  *-algebras [PDF]

open access: yesJournal of Mathematical Physics, 2008
After an appropriate restatement of the Gelfand–Naimark–Segal construction for topological  *-algebras we prove that there exists an isomorphism among the set Cycl(A) of weakly continuous strongly cyclic  *-representations of a barreled dual-separable  *-algebra with unit A, the space HilbA(A*) of the Hilbert spaces that are continuously embedded in A*

Coequalizers and pullbacks in the category Seg of Segal topological algebras [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2021
In this paper we describe the coequalizers in the category Seg of Segal topological algebras and present some sufficient conditions for the existence of pullbacks in Seg.

About the transitivity of the property of being Segal topological algebra

open access: yesActa et Commentationes Universitatis Tartuensis de Mathematica, 2022
We show that if (A, f, B) and (B, g, C) are left (right or two-sided) Segal topological algebras for which g(f(A))⊆ g(B)g(f(A))  (g(f(A))⊆ g(f(A))g(B)  or  g(f(A))⊆ g(B)g(f(A))∩ g(f(A))g(B), respectively), then (A, g∘ f, C) is also a left (right or two-sided, respectively) Segal topological algebra.

About the cocompleteness of the category S(B) of Segal topological algebras

open access: yesProceedings of the Estonian Academy of Sciences, 2020
In this paper, we show that the category S(B) of Segal topological algebras is cocomplete, i.e., that the colimits of all direct systems in the category S(B) exist.

About the limits of inverse systems in the category S(B) of Segal topological algebras

open access: yesProceedings of the Estonian Academy of Sciences, 2020
In this paper, we give a necessary condition for the existence of limits of all inverse systems and a sufficient condition for the existence of limits for all countable inverse systems in the category S(B) of Segal topological algebras.

Higher representation stability for ordered configuration spaces

open access: yesJournal of Topology, Volume 19, Issue 3, September 2026.
Abstract Using factorization homology with coefficients in twisted commutative algebras (TCAs), we prove two flavors of higher representation stability for the cohomology of (generalized) configuration spaces of a scheme/topological space X$X$. First, we provide an iterative procedure to study higher representation stability using actions coming from ...
