The theory of almost periodic functions was introduced in the literature around 1924–1926 with the pioneering work of the Danish mathematician Bohr [25]. A decade later, various significant contributions were then made to that theory mainly by Bochner [24], von Neumann [159], and van Kampen [155]. The notion of almost periodicity, which generalizes the

Weakly Almost-Periodic Functions
1971Let X be a Banach space and X* the dual space. Let x denote the elements of X, x* the elements of X* (continuous linear functionals on X), ||x|| and ||x*|| the respective norms.

Measurable almost periodic functions
Mathematika, 1956A complex-valued function ƒ is said by W. Maak [1] to be almost periodic (a.p.) on R n if for every positive number e there is a decomposition of R n into a finite number of sets S such that for all h in R n and all pairs x , y belonging to the same S . This definition is equivalent to that of Bohr when ƒ is continuous.

Discontinuous Almost Periodic Functions
2019This chapter is a basic for the book, since it considers not only discontinuous almost periodic functions, which are initial in the research of differential equations with different types of discontinuity, but also unbounded number sequences which are common instruments to introduce and analyze discontinuities not only in impulsive systems, but also in
