Nonresonance Conditions for the Existence of Almost Periodic Solutions of Almost Periodic Systems

SIAM Journal on Applied Mathematics, 1971
For complex systems of the form \[ x' = Ax + \varepsilon g( {t,x,\varepsilon } ) , \] where A is a square matrix, g is analytic in the components of x and almost periodic in t, and $\varepsilon $ is a complex parameter, we give conditions on the Fourier exponents of g and the eigenvalues of A such that for $\| \varepsilon |$ sufficiently small, the ...

Asymptotically almost periodic, almost periodic and pseudo-almost periodic mild solutions for neutral differential equations

Nonlinear Analysis: Real World Applications, 2010
Results concerning existence and uniqueness of almost periodic, asymptotically almost periodic, and pseudo-almost periodic mild solutions are provided for the following neutral differential equation in a Banach space \(X\) \[ \frac{d}{dt}\;u(t)=Au(t) + \frac{d}{dt}\;F_1(t, u(h_1(t))) + F_2(t,u(h_2(t))), \quad t\in \mathbb{R}, \] where \(A\) is the ...

On P systems and almost periodicity

Fundam. Informaticae, 2005
Summary: The study of P systems as a mathematical model for biological systems is an important research topic in the area of membrane computing. In this respect, the detection of periodicity and almost periodicity as aspects of the system dynamics seems to be of particular relevance for understanding many biological processes and their related ...

Periodic and Almost Periodic Motions

1967
By Def. 38.1 a motion described by p(t, a, t0) is called periodic with period ω if for all t ≥ t0 the relation $$ {\rm{ }}(t{\rm{ }} + {\rm{ }}\omega ,{\rm{ }}a, {t_0}){\rm{ }} = {\rm{ }}p{\rm{ }}(t,{\rm{ }}a, {t_0}) $$ (71.1) is satisfied.
