Crystalline gauge fields and quantized discrete geometric response for Abelian topological phases with lattice symmetry

open access: yesPhysical Review Research, 2021
Clean isotropic quantum Hall fluids in the continuum possess a host of symmetry-protected quantized invariants, such as the Hall conductivity, shift, and Hall viscosity.

A Note on the Generalized Nonlinear Vector Variational-Like Inequality Problem

open access: yesJournal of Function Spaces, 2021
In this paper, we discuss two variants of the generalized nonlinear vector variational-like inequality problem. We provide their solutions by adopting topological approach.

On the Relationship between Primal/Dual Cell Complexes of the Cell Method and Primal/Dual Vector Spaces: an Application to the Cantilever Elastic Beam with Elastic Inclusion

open access: yesCurved and Layered Structures, 2019
The Cell Method (CM) is an algebraic numerical method based on the use of global variables: the configuration, source and energetic global variables. The configuration variables with their topological equations, on the one hand, and the source variables ...

Weak Darboux property and transitivity of linear mappings on topological vector spaces

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2013
It is shown that every linear mapping on topological vector spaces always has weak Darboux property, therefore, it is continuous if and only if it is transitive.

Menger probabilistic normed space is a category topological vector space [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2016
In this paper, we formalize the Menger probabilistic normed space as a category in which its objects are the Menger probabilistic normed spaces and its morphisms are fuzzy continuous operators.

A characterization of singular endomorphisms of a barrelled Pták space

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1982
The concept of topological divisor of zero has been extended to endomorphisms of a locally convex topological vector space (LCTVS). A characterization of singular endomorphisms, similar to that of Yood [1], is obtained for endomorphisms of a barrelled ...

Topological Vector-Space Valued Cone Banach Spaces

open access: yesInternational Journal of Analysis and Applications, 2014
In this paper we introduce the notion of tvs-cone normed spaces, discuss related topological concepts and characterize the tvs-cone norm in various directions. We construct generalize locally convex tvs generated by a family of tvs-cone seminorms.

Photonic helicoid-like surface states in chiral metamaterials

open access: yesScientific Reports, 2023
We investigate the photonic topological phases in chiral metamaterials characterized by the magnetoelectric tensors with diagonal chirality components. The underlying medium is considered a photonic analogue of the topological semimetal featured with a ...

Derivative for Functions f:GH, Where G Is a Metric Divisible Group

open access: yesMathematics, 2022
In this paper, a derivative for functions f:G→H, where G is any metric divisible group and H is a metric Abelian group with a group metric, is defined. Basic differentiation theorems are stated and demonstrated. In particular, we obtain the Chain Role.

Common Fixed Points for Maps on Topological Vector Space Valued Cone Metric Spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2009
We introduced a notion of topological vector space valued cone metric space and obtained some common fixed point results. Our results generalize some recent results in the literature.
