In this paper, we analyze several various classes of Stepanov multi-dimensional almost periodic functions in Lebesgue spaces with variable exponents. The introduced classes seem to be new and not ...

Almost automorphic functions extend the classical concept of almost periodicity to a more flexible framework that accommodates non‐uniform recurrence in differential equations. These solutions emerge ...
