The Second Hyper-Zagreb Coindex of Chemical Graphs and Some Applications

open access: yesJournal of Chemistry, 2021
The second hyper-Zagreb coindex is an efficient topological index that enables us to describe a molecule from its molecular graph. In this current study, we shall evaluate the second hyper-Zagreb coindex of some chemical graphs. In this study, we compute

Quantum phase transition between symmetry enriched topological phases in tensor-network states

open access: yesPhysical Review Research, 2023
Quantum phase transitions between different topologically ordered phases exhibit rich structures and are generically challenging to study in microscopic lattice models.

Wiener Polarity Index of Tensor Product of Graphs [PDF]

open access: yesMathematics Interdisciplinary Research, 2016
Mathematical chemistry is a branch of theoretical chemistry for discussion and prediction of the molecular structure using mathematical methods without necessarily referring to quantum mechanics.

Algebraic Representation of Topologies on a Finite Set

open access: yesMathematics, 2022
Since the 1930s, topological counting on finite sets has been an interesting work so as to enumerate the number of corresponding order relations on the sets.

Homological support of big objects in tensor-triangulated categories [PDF]

open access: yesJ. \'Ec. polytech. Math. 7 (2020), 1069-1088, 2020
Using homological residue fields, we define supports for big objects in tensor-triangulated categories and prove a tensor-product formula.

Twisted string theory in anti-de Sitter space

open access: yesJournal of High Energy Physics, 2020
We construct a string theory in three-dimensional anti-de Sitter space-time that is independent of the boundary metric. It is a topologically twisted theory of quantum gravity. We study string theories with an asymptotic N = 2 superconformal symmetry and

On the joint continuity of module multiplication [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2023
Let A be any topological algebra over R or C. We show that the property of a topological left (right or two-sided) A-module to have a jointly continuous action of A is inherited by submodules, quotient modules, completion, direct products, direct sums ...

A Mysterious Tensor Product in Topology

open access: yes, 2022
We describe the construction of the tensor product of topological operads introduced by Boardman and Vogt, and explain some questions about it that have been puzzling Vogt and others for many years.

BPS skyrmions of generalized Skyrme model in higher dimensions

open access: yesJournal of High Energy Physics, 2022
In this work we consider the higher dimensional Skyrme model, with spatial dimension d > 3, focusing on its BPS submodels and their corresponding features.
