Knot Invariants and New Weight Systems from General 3D TFTs [PDF]

open access: yes, 2011
We introduce and study the Wilson loops in a general 3D topological field theories (TFTs), and show that the expectation value of Wilson loops also gives knot invariants as in Chern-Simons theory.

Fast Loop Closure Selection Method with Spatiotemporal Consistency for Multi-Robot Map Fusion

open access: yesApplied Sciences, 2022
This paper presents a robust method based on graph topology to find the topologically correct and consistent subset of inter-robot relative pose measurements for multi-robot map fusion.

Graph Reconstruction by Discrete Morse Theory [PDF]

open access: yesInternational Symposium on Computational Geometry, 2018
Recovering hidden graph-like structures from potentially noisy data is a fundamental task in modern data analysis. Recently, a persistence-guided discrete Morse-based framework to extract a geometric graph from low-dimensional data has become popular ...

Evaluation of Changes in the Motor Network Following BCI Therapy Based on Graph Theory Analysis

open access: yesFrontiers in Neuroscience, 2018
Despite the established effectiveness of the brain-computer interface (BCI) therapy during stroke rehabilitation (Song et al., 2014a, 2015; Young et al., 2014a,b,c, 2015; Remsik et al., 2016), little is understood about the connections between motor ...

Unquenched flavor and tropical geometry in strongly coupled Chern-Simons-matter theories [PDF]

open access: yes, 2011
We study various aspects of the matrix models calculating free energies and Wilson loop observables in supersymmetric Chern-Simons-matter theories on the three-sphere.

Analysis of a planetary gear modelled with a contour graph considering the decision making complexity of game-tree structures

open access: yesITM Web of Conferences, 2017
Analysis and synthesis of mechanisms is one of the fundamental tasks of engineering. Mechanisms can suffer from errors due to versatile reasons. Graph-based methods of analysis and synthesis of planetary gears constitute an alternative method for ...

Color/kinematics duality for general abelian orbifolds of N=4 super Yang-Mills theory [PDF]

open access: yes, 2014
To explore color/kinematics duality for general representations of the gauge group we formulate the duality for general abelian orbifolds of the SU(N), N=4 super Yang-Mills theory in four dimensions, which have fields in the bi-fundamental representation,

Network dismantling on factor graphs: break long loops and spare local structures

open access: yesNew Journal of Physics, 2021
A new solution framework for the task of network dismantling is recently developed, based on a two-scale bipartite factor-graph representation of the original graph where local structures are abstracted as factor nodes.

Making multigraphs simple by a sequence of double edge swaps

open access: yes, 2021
We show that any loopy multigraph with a graphical degree sequence can be transformed into a simple graph by a finite sequence of double edge swaps with each swap involving at least one loop or multiple edge.
