Lines, betweenness and metric spaces
Pierre Aboulker, Xiaomin Chen, Guangda Huzhang +2
A classic theorem of Euclidean geometry asserts that any noncollinear set of points in the plane determines at least distinct lines. Chen and Chvátal conjectured that this…
The partition function of the extended -reduced Kadomtsev-Petviashvili hierarchy
Marco Bertola, Di Yang
We derive a particular solution of the extended -reduced KP hierarchy, which is specified by a generalized string equation. The work is a generalization to arbitrary o…
Soft and hard confinement of a two-electron quantum system
Richard L. Hall, Nasser Saad, K. D. Sen
A model physical problem is studied in which a system of two electrons is subject either to soft confinement by means of attractive oscillator potentials or by entrapment within an…
Schrödinger spectrum generated by the Cornell potential
Richard L. Hall, Nasser Saad
The eigenvalues of the -dimensional Schrödinger equation with the Cornell potential , are analyzed by means of the envelope method and…
Simple Subroutine for Inhomogeneous Deployment
Mouhamed Abdulla
Spatial modeling of wireless networks via analytical means has been considered as a widely practiced mechanism for inference. As a result, some geometrical deployment models have b…
Optimal online and offline algorithms for robot-assisted restoration of barrier coverage
J. Czyzowicz, E. Kranakis, D. Krizanc +2
Cooperation between mobile robots and wireless sensor networks is a line of research that is currently attracting a lot of attention. In this context, we study the following proble…
