No periodic orbits for the type A Bianchi's systems
(Taylor & Francis Ltd, 2015-01-01)
It is known that the 6 models of Bianchi class A have no periodic solutions. In this article we provide a new, direct, unified and easier proof of this result.
Stability properties of periodic traveling waves for the intermediate long wave equation
(European Mathematical Soc, 2017-01-01)
In this paper we determine orbital and linear stability of a class of spatially periodic wavetrain solutions with the mean zero property related to the intermediate long wave equation. Our arguments follow recent developments ...
A note on the stability and instability of travelling wave of Korteweg-de Vries type : the periodic case.
(2012-10-04)
In this paper we adapt the work of M. Grillakis, J. Shatah, and W. Strauss, or J. Bona, P.
Souganidis and W. Strauss to the periodic case in spaces having the mean zero property in order
to establish the orbital ...
Existence of positive T-periodic solutions of a generalized Nicholson’s blowflies model with a nonlinear harvesting term
(Elsevier, 2012-09)
We give sufficient and necessary conditions for the existence of at least one positive T -periodic solution for a generalized Nicholson’s blowflies model with a nonlinear harvesting term. Our results extend those of the ...
Local attractors, degeneracy and analyticity: Symmetry effects on the locally coupled Kuramoto model
(2013-04-02)
In this work we study the local coupled Kuramoto model with periodic boundary conditions. Our main objective is to show how analytical solutions may be obtained from symmetry assumptions, and while we proceed on our endeavor ...

Emergence of log-periodic oscillations in periodic and aperiodic Ising models
(Sociedade Brasileira de Física, 2000-12)
This work analyzes the emergence of log-periodic oscillations in thermodynamic functions of Ising models on hierarchical lattices. Several situations, where the exchange interactions are periodic or aperiodic, are taken ...

One-dimensional multi-period cutting stock problems in the concrete industry
(2021-01-01)
This research looks at the production planning of hollow-core slabs integrated to the optimisation problem of the use of moulds. Considering the production process of these structures, two mathematical models are proposed ...
