M-Polynomials and Degree-Based Topological Indices of the Molecule Copper(I) Oxide
Journal of Chemistry, 2021 Topological indices are numerical parameters used to study the physical and chemical residences of compounds. Degree-based topological indices have been studied extensively and can be correlated with many properties of the understudy compounds.

Topological transcendence degree [PDF]
Journal of Algebra, 2021 Throughout the paper, an analytic field means a non-archimedean complete real-valued one, and our main objective is to extend to these fields the basic theory of transcendental extensions. One easily introduces a topological analogue of the transcendence degree, but, surprisingly, it turns out that it may behave very badly.

Existence of solutions to second-order boundary value problems without growth restrictions
Electronic Journal of Qualitative Theory of Differential Equations, 2016 This article investigates nonlinear, second-order ordinary differential equations subject to various two-point boundary conditions. A condition is introduced that ensures a priori bounds on the derivatives of solutions to the problem.

Enumeration Degrees and Topology [PDF]
, 2018 The study of enumeration degrees appears prima facie to be far removed from topology. Work by Miller, and subsequently recent work by Kihara and the author has revealed that actually, there is a strong connection: Substructures of the enumeration degrees correspond to \(\sigma \)-homeomorphism types of second-countable topological spaces.

On \(ev\)-degree and \(ve\)-degree topological indices
, 2017 Summary: Recently, two new degree concepts have been defined in graph theory: \(ev\)-degree and \(ve\)-degree. Also the \(ev\)-degree and \(ve\)-degree Zagreb and Randić indices have been defined very recently as parallel of the classical definitions of Zagreb and Randić indices. It was shown that \(ev\)-degree and \(ve\)-degree topological indices can

Convergence Classes of L-Filters in L,M-Fuzzy Topological Spaces
Journal of Mathematics, 2021 An L,M-fuzzy topological convergence structure on a set X is a mapping which defines a degree in M for any L-filter (of crisp degree) on X to be convergent to a molecule in LX.
