Applied General Topology, 2021 Let C∞ (X) denote the family of real-valued continuous functions which vanish at infinity in the sense that {x ∈ X : |f(x)| ≥ 1/n} is compact in X for all n ∈ N. It is not in general true that C∞ (X) is an ideal of C(X).

Journal of Function Spaces, 2021 In this article, we define a new sequence space generated by the domain of r-Cesàro matrix in Nakano sequence space. Some geometric and topological properties of this sequence space, the multiplication maps defined on it, and the eigenvalue distributions

Hidden Zeeman Field in Odd-Parity Magnets: An Ideal Platform for Topological Superconductivity. [PDF]
Physical Review LettersOdd-parity magnets (OPMs) have emerged as a fundamental class of unconventional magnetism, characterized by time-reversal-preserving nonrelativistic spin splitting (NSS).

Topological States of Matter [PDF]
, 2012 My research program is focused on the study of elastic deformation and topological defects in two materials: graphene and topological insulators. In both systems at low energies the electrons have a nearly linear spectrum, i.e.

European Journal of Pure and Applied MathematicsThis paper presents new concepts of continuous multifunctions defined from an ideal topological space into a bitopological space, called upper $\tau^\star(\sigma_1,\sigma_2)$-continuous multifunctions and lower $\tau^\star(\sigma_1,\sigma_2)$-continuous ...

g_*^*-I-Closed Sets and Their Properties in in Ideal Topological Space [PDF]
المجلة العراقية للعلوم الاحصائيةThere are many research papers that deal with different types of generalized closed sets. Levine [4] introduced generalized closed (briefly, -closed) sets and studied their basic properties and Veera Kumar [5] introduced -closed sets in topological ...

Soft Semi Local Functions in Soft Ideal Topological Spaces
European Journal of Pure and Applied Mathematics, 2019 In this paper, we define a soft semi local function (F, E) ∗s ( ˜I, τ ) by using semi open soft sets in a soft ideal topological space (X, τ, E, ˜I). This concept is discussed with a view to find new soft topologies from the original one, called ∗

Ideal type-II Weyl points in topological circuits [PDF]
National Science Review, 2019 Weyl points (WPs), nodal degenerate points in three-dimensional (3D) momentum space, are said to be ‘ideal’ if they are symmetry-related and well-separated, and reside at the same energy and far from nontopological bands. Although type-II WPs have unique
