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 ...

In this paper the positive and strictly contractive extension problems for almost periodic matrix functions are treated. We present necessary and sufficient conditions for the existence of extensions ...

The Collatz conjecture is an open problem involving the 3x + 1 function. The function belongs to a class of generalized 3x + 1 functions of relatively prime type. This paper focuses on exploring ...
