The Method of Zero Tangential Strengths in the Problem of Charge Distribution over the Surfaces of Two Interacting Tori [PDF]

Journal of Applied and Computational Mechanics
In this paper, a system of two circular concentric non-touching tori is considered. An electrostatic charge can be applied to each of the tori. The problem is to find the density of charge distribution over the surfaces of the tori, taking into account ...

Doubly semi-equivelar maps on the plane and the torus

AKCE International Journal of Graphs and Combinatorics, 2022
A map is called 2-semi equivelar if it has exactly two distinct cyclic arrangement of faces at its vertices. A 2-semi-equivelar map is called 2-uniform if it has precisely 2 orbits of vertices under its symmetric group.

On the Isometric Path Partition Problem

Discussiones Mathematicae Graph Theory, 2021
The isometric path cover (partition) problem of a graph consists of finding a minimum set of isometric paths which cover (partition) the vertex set of the graph.

El motivo del lecho conyugal en la Alcestis Barcinonensis: dos notas de lectura

Emerita, 2011
En este trabajo se estudia la centralidad del motivo amatorio del lecho conyugal en el poema anónimo Alcestis Barcinonensis, a la luz de lo cual se ofrecen dos nuevas interpretaciones de los versos 21-22 y 83-85.

Making Clean Energy with a Kerr Black Hole: a Tokamak Model for Gamma-Ray Bursts

, 2000
In this paper we present a model for making clean energy with a Kerr black hole. Consider a Kerr black hole with a dense plasma torus spinning around it.

The Contribution of the Obscuring Torus to the X--Ray Spectrum of Seyfert Galaxies: A Test for the Unification Model [PDF]

, 1994
The presence of an obscuring torus around the nucleus of Seyfert galaxies, as supposed in the popular unification scheme, can strongly modify the X--ray spectrum for both type 1 and 2 Seyfert galaxies.

Backreaction I: The torus [PDF]

Nuclear Physics B, 2001
We use wrapped D-brane probes to measure position dependent perturbations of compactification moduli. Due to the backreaction of the D-branes on the local geometry, we suspect that measuring the fluctuations of one modulus to high precision will generically affect the others.

One Can Hear the Area of a Torus by Hearing the Eigenvalues of the Polyharmonic Operators

Demonstratio Mathematica, 2014
This paper considers the asymptotic properties for the spectrum of a positive integer power l of the Laplace-Beltrami operator acting on an n-dimensional torus T.

Hierarchical Wave Functions Revisited

, 1997
We study the hierarchical wave functions on a sphere and on a torus. We simplify some wave functions on a sphere or a torus using the analytic properties of wave functions.

ON POLYNOMIAL TORUS KNOTS [PDF]

Journal of Knot Theory and Its Ramifications, 2008
We show that no torus knot of type (2, n), n > 3 odd, can be obtained from a polynomial embedding t ↦ (f(t), g(t), h(t)) where (deg(f), deg(g)) ≤ (3, n + 1). Eventually, we give explicit examples with minimal lexicographic degree.
