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.

Asymptotic topology [PDF]

open access: yes, 1999
We establish some basic theorems in dimension theory and absolute extensor theory in the coarse category of metric spaces. Some of the statements in this category can be translated in general topology language by applying the Higson corona functor.

On power-law relationships of the Internet topology

open access: yesConference on Applications, Technologies, Architectures, and Protocols for Computer Communication, 1999
Despite the apparent randomness of the Internet, we discover some surprisingly simple power-laws of the Internet topology. These power-laws hold for three snapshots of the Internet, between November 1997 and December 1998, despite a 45% growth of its ...

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 Expansion, Study and Applications [PDF]

open access: yesTopology and its Applications, 160, p 2121-2139 , (2013), 2012
In this paper, we introduce the notion of expanding topological space. We define the topological expansion of a topological space via local multi-homeomorphism over coproduct topology, and we prove that the coproduct family associated to any fractal family of topological spaces is expanding.

Dynamic GCN: Context-enriched Topology Learning for Skeleton-based Action Recognition [PDF]

open access: yesACM Multimedia, 2020
raph Convolutional Networks (GCNs) have attracted increasing interests for the task of skeleton-based action recognition. The key lies in the design of the graph structure, which encodes skeleton topology information.

Topological Structures on DMC spaces [PDF]

open access: yes, 2017
Two channels are said to be equivalent if they are degraded from each other. The space of equivalent channels with input alphabet $X$ and output alphabet $Y$ can be naturally endowed with the quotient of the Euclidean topology by the equivalence relation.

Topological magnetoplasmon [PDF]

open access: yesNature Communications, 2016
AbstractClassical wave fields are real-valued, ensuring the wave states at opposite frequencies and momenta to be inherently identical. Such a particle–hole symmetry can open up new possibilities for topological phenomena in classical systems. Here we show that the historically studied two-dimensional (2D) magnetoplasmon, which bears gapped bulk states
