On mc‐hop Connectedness in the Monophonic c‐topological Spaces: Applications on Some Networks in the Human Optical System

open access: yesJournal of Mathematics, Volume 2026, Issue 1, 2026.
In this paper, we introduce the concept of mc‐vertices in simple graphs and use monophonic paths to define a new class of vertex topologies, called monophonic c‐topologies. We investigate fundamental properties of these spaces, including openness‐minimizing behavior, compactness, and various forms of connectedness, and we characterize graphs that ...

Generalized α‐Attractor Models from Elementary Hyperbolic Surfaces

open access: yesAdvances in Mathematical Physics, Volume 2018, Issue 1, 2018., 2018
We consider generalized α‐attractor models whose scalar potentials are globally well‐behaved and whose scalar manifolds are elementary hyperbolic surfaces. Beyond the Poincaré disk D, such surfaces include the hyperbolic punctured disk D⁎ and the hyperbolic annuli A(R) of modulus μ = 2log⁡R > 0. For each elementary surface, we discuss its decomposition

PRE-ALEXANDROFF SPACE

open access: yesUniversity of Thi-Qar Journal of Science, 2013
In this paper we introduce a new definition of the topological space weaker of Alexandroff space, namely pre-Alexandroff space. These spaces are which arbitrary intersection of an open set is a pre-open set. In addition to give a new definition of minimal pre-open sets and investigate about some of its properties, also we get some theorems and result ...

On Various Modes of Convergence and Notions of Exhaustiveness With Korovkin‐Type Theorems

open access: yesJournal of Mathematics, Volume 2026, Issue 1, 2026.
In this paper, we introduce refined notions related to convergence and exhaustiveness for sequences of functions defined between metric spaces. These include rigid uniform alpha convergence as a strengthened variant of alpha convergence, along with uniform sequential exhaustiveness, rigid uniform exhaustiveness, Cauchy exhaustiveness, and rigid Cauchy ...

Orlicz Mean Dual Affine Quermassintegrals

open access: yesJournal of Function Spaces, Volume 2018, Issue 1, 2018., 2018
Our main aim is to generalize the mean dual affine quermassintegrals to the Orlicz space. Under the framework of dual Orlicz‐Brunn‐Minkowski theory, we introduce a new affine geometric quantity by calculating the first Orlicz variation of the mean dual affine quermassintegrals and call it the Orlicz mean dual affine quermassintegral.

On Shehtman's two problems

open access: yesJournal of the London Mathematical Society, Volume 111, Issue 3, March 2025.
Abstract We provide partial solutions to two problems posed by Shehtman concerning the modal logic of the Čech–Stone compactification of an ordinal space. We use the Continuum Hypothesis to give a finite axiomatization of the modal logic of β(ω2)$\beta (\omega ^2)$, thus resolving Shehtman's first problem for n=2$n=2$. We also characterize modal logics

The Mumford conjecture (after Bianchi)

open access: yesJournal of Topology, Volume 18, Issue 1, March 2025.
Abstract We give a self‐contained and streamlined rendition of Andrea Bianchi's recent proof of the Mumford conjecture using moduli spaces of branched covers.

A Characterization of Affine Primal Topological Spaces Induced by Nilpotent Matrices

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2025, Issue 1, 2025.
In this article, we prove that an n × n matrix A is nilpotent if and only if there exists an affine primal topology τ for Rn such that the space Rn,τ is both compact and connected. For τ being an affine primal topology, we mean that τ=U⊂Rn:f−1U⊂U, where f:Rn⟶Rn is a map defined by f(x) = Ax + p, with p∈Rn.

Parabolic isometries of the fine curve graph of the torus

open access: yesProceedings of the London Mathematical Society, Volume 129, Issue 2, August 2024.
Abstract In this article, we finish the classification of actions of torus homeomorphisms on the fine curve graph initiated by Bowden, Hensel, Mann, Militon, and Webb. This is made by proving that if f∈Homeo(T2)$f \in \mathrm{Homeo}(\mathbb {T}^2)$, then f$f$ acts elliptically on C†(T2)$\mathcal {C}^{\dagger }(\mathbb {T}^2)$ if and only if f$f$ has ...
