Periodicity of Rauzy scheme and substitutional systems
combinatorics on words periodicity Bernside type problems periodicity
2011/8/22
Abstract: In the paper the notion of {\em Rauzy scheme} is introduced. From Rauzy graph Rauzy Scheme can be obtaining by uniting sequence of vertices of ingoing and outgoing degree 1 by arches. This n...

Computing (or not) Quasi-Periodicity Functions Tilings
2011/3/2
We know that tilesets that can tile the plane always admit a quasiperiodic tiling [4, 8], yet they hold many uncomputable properties [3, 11, 21, 25].The quasi-periodicity function is one way to measur...

A new periodicity concept for time scales
Periodic time scale periodic function shift operator
2011/1/20
By means of the shift operators we introduce a new periodicity concept on time scales. This new approach will enable researchers to investigate periodicity notion on a large class of time scales whose...
In this note we show that the restriction of the cotangent bundle $\Omega_{\mathbb P}^2$ of the projective plane to a Fermat curve $C$ of degree $d$ in characteristic $p \equiv -1 \mod 2d$ is, up to t...
On the range, local times and periodicity of random walk on an interval
range random walk local times periodicity
2010/12/9
The range, local times, and periodicity of symmetric, weakly asymmetric and asymmetric random walks at the time of exit from a strip with N locations are considered. Several results on asymptotic dist...
PERIODICITY FOR A COOPERATIVE SYSTEM ON TIME SCALES
time scales cooperative system coincidence degree continuation theorem periodic solutions
2008/11/28
In this paper, by using the method of coincidence degree theory, we explore the existence
of periodic solutions for a cooperative ecological model on time scales.

Periodic solutions toxicants time delays
2007/12/10
With the help of a continuation theorem based on Gaines and Mawhin's coincidence degree, we study the global existence of positive periodic solutions of a "food-limited population model with toxicants...
Solution formula and time periodicity for the motion of relativistic strings in the Minkowski space R1+n
Equations for the motion of relativistic string general solution formula generalized periodic function characteristic-quadrilateral identity
2018/4/20
In this paper we study the motion of relativistic strings in the Minkowski space R1+n which is governed by n nonlinear partial di甧rential equations of second order. Surprisingly, we obtain a general s...
