Cauchy matrix for linear almost periodic systems and some consequences
(2011)
A novel method to construct the fundamental matrix for a linear almost periodic system is proposed, provided that the diagonal terms satisfy an average separation condition and the off-diagonal coefficients are L∞- small. ...
Linearly repetitive delone systems have afinite number of non periodic delone system factors

Some applications of periodic orbits for competitive systems

Multiple solutions for periodic perturbations of a delayed autonomous system near an equilibrium
(American Institute of Mathematical Sciences, 2019)
Small non-autonomous perturbations around an equilibrium of a nonlinear delayed system are studied. Under appropriate assumptions, it is shown that the number of T-periodic solutions lying inside a bounded domain Ω ⊂ R N ...
On the existence and stability of periodic orbits in non ideal problems: General results
(2007-11-01)
In this work, motivated by non-ideal mechanical systems, we investigate the following O.D.E. ẋ = f (x) + εg (x, t) + ε2g (x, t, ε), where x ∈ Ω ⊂ ℝn, g, g are T periodic functions of t and there is a 0 ∈ Ω such that f (a ...

Controllability and stabilizability of linear time-varying distributed hereditary control systems
(2014)
This paper is concerned with the controllability and stabilizability problem for control systems described by a time-varyinglinear abstract differential equation with distributed delay in the state variables. An approximate ...
On an Optimal Linear Control Applied to a Non-Ideal Load Transportation System, Modeled with Periodic Coefficients

Almost periodic evolution systems with impulse action at state-dependent moments
(Academic Press Inc., 2017)
© 2016 Elsevier Inc. We study the existence of almost periodic solutions for semi-linear abstract parabolic evolution equations with impulse action at state-dependent moments. In particular, we present conditions excluding ...
The local period function for Hamiltonian systems with applications
(Elsevier B.V., 2021-04-15)
In the first part of the paper we develop a constructive procedure to obtain the Taylor expansion, in terms of the energy, of the period function for a non-degenerated center of any planar analytic Hamiltonian system. We ...
