Reducibility of systems and existence of solutions for almost periodic differential equations

open access: yesElectronic Journal of Differential Equations, 2012
We establish the reducibility of linear systems of almost periodic differential equations into upper triangular systems of a. p. differential equations. This is done while the number of independent a. p. solutions is conserved. We prove existence and

‘Almost nonunique’ solutions to parameter estimation in periodic signals

open access: yesEURASIP Journal on Advances in Signal Processing
Provided the Nyquist criterion is met, by the Nyquist–Shannon sampling theorem one can reconstruct the signal uniquely using the sampled data. In this work, by means of an algorithm that computes the amplitudes, frequencies and phases of a signal to ...

Weighted pseudo almost periodic solutions for functional differential equations

open access: yesElectronic Journal of Differential Equations, 2007
By means of the exponential dichotomy method and the properties of the weighted pseudo almost periodic functions, sufficient conditions are obtained for the existence of weighted pseudo almost periodic solutions of functional differential equations ...
