The geometry and combinatorics of discrete line segment hypergraphs [PDF]
Discrete Mathematics, 2020 An $r$-segment hypergraph $H$ is a hypergraph whose edges consist of $r$ consecutive integer points on line segments in $\mathbb{R}^2$. In this paper, we bound the chromatic number $χ(H)$ and covering number $τ(H)$ of hypergraphs in this family, uncovering several interesting geometric properties in the process.

Discrete Gradient Line Fields on Surfaces
CoRR, 2017 A line field on a manifold is a smooth map which assigns a tangent line to all but a finite number of points of the manifold. As such, it can be seen as a generalization of vector fields. They model a number of geometric and physical properties, e.g. the principal curvature directions dynamics on surfaces or the stress flux in elasticity.

The Solvability of the Discrete Boundary Value Problem on the Half-Line
Entropy, 2021 This paper provides conditions for the existence of a solution to the second-order nonlinear boundary value problem on the half-line of the form Δa(n)Δx(n)=f(n+1,x(n+1),Δx(n+1)),n∈N∪{0}, with αx(0)+βa(0)Δx(0)=0,x(∞)=d, where d,α,β∈R, α2+β2>0.

A Discrete Transmission Line Model for Discrete-time Quantum Walks
Interdisciplinary Information Sciences, 2017 Summary: Based on the similarity between telegraph equation for transmission lines and Klein-Gordon equation, we have related a distributed element model in electrical engineering to a discrete-time quantum walk through Dirac equation. As a result, we have constructed a discrete transmission line model for a discrete-time quantum walk, and it enables ...
