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

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 finnicky equations ...

This chapter introduces the Fourier series representation of continuous time periodic functions. A periodic function can be represented as a vector in an infinite‐dimensional space. Harmonically ...
