On the Wiener Complexity and the Wiener Index of Fullerene Graphs

open access: yesMathematics, 2019
Fullerenes are molecules that can be presented in the form of cage-like polyhedra, consisting only of carbon atoms. Fullerene graphs are mathematical models of fullerene molecules.

Minimum topological group topologies [PDF]

open access: yesJournal of Pure and Applied Algebra, 2017
A Hausdorff topological group topology on a group $G$ is the minimum (Hausdorff) group topology if it is contained in every Hausdorff group topology on $G$. For every compact metrizable space $X$ containing an open $n$-cell, $n\ge2$, the homeomorphism group $H(X)$ has no minimum Hausdorff group topology.

ICrAData - Software for InterCriteria Analysis [PDF]

open access: yesInternational Journal Bioautomation, 2018
In this paper, we consider the InterCriteria Analysis (ICrA), which is based on the index matrices and intuitionistic fuzzy sets. We demonstrate the application of ICrA using the software ICrAData.

Topological Blockade and Measurement of Topological Charge [PDF]

open access: yesPhysical Review Letters, 2013
The fractionally charged quasiparticles appearing in the 5/2 fractional quantum Hall plateau are predicted to have an extra non-local degree of freedom, known as topological charge. We show how this topological charge can block the tunnelling of these particles, and how such 'topological blockade' can be used to readout their topological charge.
