Chromatically unique 6-bridge graph theta(a, a, a, b, b, c)

open access: yesElectronic Journal of Graph Theory and Applications, 2016
For a graph $G$, let $P(G,\lambda)$ denote the chromatic polynomial of $G$. Two graphs $G$ and $H$ are chromatically equivalent if they share the same chromatic polynomial. A graph $G$ is chromatically unique if for any graph chromatically equivalent to $

Duality properties of indicatrices of knots

open access: yes, 2012
The bridge index and superbridge index of a knot are important invariants in knot theory. We define the bridge map of a knot conformation, which is closely related to these two invariants, and interpret it in terms of the tangent indicatrix of the knot ...

Robust Transport over Networks [PDF]

open access: yes, 2017
We consider transportation over a strongly connected, directed graph. The scheduling amounts to selecting transition probabilities for a discrete-time Markov evolution which is designed to be consistent with initial and final marginal constraints on mass

Bridge Network Seismic Risk Assessment Using ShakeMap/HAZUS with Dynamic Traffic Modeling

open access: yesInfrastructures, 2022
Bridge infrastructures are critical nodes in a transportation network. In earthquake-prone areas, seismic performance assessment of infrastructure is essential to identify, retrofit, reconstruct, or, if necessary, demolish the infrastructure systems ...

A Simplicial Complex Model for Dynamic Epistemic Logic to study Distributed Task Computability [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2018
The usual epistemic model S5n for a multi-agent system is based on a Kripke frame, which is a graph whose edges are labeled with agents that do not distinguish between two states.

K6minors in 6-connected graphs of bounded tree-width [PDF]

open access: yes, 2017
We prove that every sufficiently large 6-connected graph of bounded tree-width either has a K6 minor, or has a vertex whose deletion makes the graph planar.

$C^*$-algebraic drawings of dendroidal sets

open access: yes, 2019
In recent years the theory of dendroidal sets has emerged as an important framework for higher algebra. In this article we introduce the concept of a $C^*$-algebraic drawing of a dendroidal set. It depicts a dendroidal set as an object in the category of
