Almost periodic functions serve as a powerful conceptual framework in analysing differential equations whose coefficients or forcing terms exhibit recurrent behaviour over time.

He, C.Y. (1992) Almost Periodic Functions and Differential Equations. Higher Education Press, Beijing. has been cited by the following article: TITLE: The Existence of Periodic Solutions of a Class of ...

Furthermore, the approximated monodromy operator might be used to provide insight in the nature of the PDDE, specially with a second order equation if the solution space is confined to a two ...

Mathieu-Functions This is a Julia language library for computing periodic Mathieu functions with arbitrary q and n values. Mathieu functions are a class of very interesting and useful, but incredibly ...

A new definition of a guiding function for functional differential equations is given, which is sometimes better for applications than the known one by Mawhin. We then prove an existence result for ...

Quasi (pseudo/approximate) periodic signals often occur in natural settings, particularly when a periodic signal is recorded with noise. In this work, we develop a new dynamical equation system to ...
