Discussiones Mathematicae - General Algebra and Applications, 2019 In this paper, we introduce the notion of topological UP-algebras and several types of subsets of topological UP-algebras, and prove the generalization of these subsets.

$\varphi$-multipliers on a class of topological algebras [PDF]
Mathematica Bohemica, 2022 In this paper, we generalize the concept of $\varphi$-multipliers on Banach algebras to a class of topological algebras. Then the characterizations of $\varphi$-multipliers are investigated in these algebras.

On non-unital locally pseudoconvex Q-algebras; pp. 324–332 [PDF]
Proceedings of the Estonian Academy of Sciences, 2019 Some equivalent conditions for a topological algebra to be a Q-algebra have been studied by several researchers. They have studied Q-algebras, mainly for unital topological algebras.

Neutrosophic Soft Topological K-Algebras [PDF]
Neutrosophic Sets and Systems, 2019 In this paper, we propose the notion of single-valued neutrosophic soft topological K-algebras. We discuss certain concepts, including interior, closure, C5-connected, super connected, Compactness and Hausdorff in singlevalued neutrosophic soft ...

Topological spectrum of elements in topological algebras; pp. 271–281 [PDF]
Proceedings of the Estonian Academy of Sciences, 2018 Properties of the sets of left, right, and two-sided topologically quasi-invertible elements, topological spectra, and topological spectral radii of elements in (not necessarily unital or commutative) topological algebras are studied.

Ford lemma for topological *-algebras; pp. 69–80 [PDF]
Proceedings of the Estonian Academy of Sciences, 2011 Several analogies of Ford lemma for topological algebras (in particular, for topological *-algebras) are proved (without using projective limits). Topological *-algebras, in which a self-adjoint element a with spA(a) â (0,â) has a self-adjoint square

Boundary and domain wall theories of 2d generalized quantum double model
Journal of High Energy Physics, 2023 The generalized quantum double lattice realization of 2d topological orders based on Hopf algebras is discussed in this work. Both left-module and right-module constructions are investigated.

Mackey Q-algebras; pp. 40–53 [PDF]
Proceedings of the Estonian Academy of Sciences, 2017 Main properties of the topology defined by a bornology on a topological linear space and main properties of Mackey Q-algebras are presented. Relationships of Mackey Q-algebras with other classes of topological algebras are described.
