ON STEPANOV-LIKE ALMOST PERIODICITY IN MIXED LEBESGUE SPACES (2023)

The main purpose of this paper is to revisit the recently analyzed class of multidimensional Stepanov almost periodic functions. We introduce and study several new classes of Stepanov-like almost periodic functions in the mixed Lebesgue spaces. We also provide a new application of multi-dimensional Stepanov almost periodic functions to the abstract nonautonomous differential equations of first order, provided that all components of the exponent p_ ∈ [1, ∞)n are equal.

METRICAL BOCHNER CRITERION AND METRICAL STEPANOV ALMOST PERIODICITY (2024)

We analyze the metrical Bochner criterion and a new class of multi-dimensional metrically Stepanov almost periodic type functions. We clarify the main structural properties for the introduced classes of functions, including the Bochner criterion, and provide certain applications to Doss-p-almost periodic functions. We also study the extensions of almost periodic sequences and briefly explain how we can apply the established theoretical results to the abstract Volterra integro-differential equation

METRICALLY ρ-ALMOST PERIODIC TYPEFUNCTIONS WITH VALUES IN LOCALLY CONVEX SPACES (2025)

We consider several new classes of metrically ρ-almost periodic type functions F: I ×X →Y, where ∅ = I ⊆ Rn, X is an arbitrary non-empty set and Y is a sequentially completelocally convex space. We briefly explain how the introduced notion can be useful in the study of qualitative analysis of solutions for some classes of the abstract Volterra integro-differential inclusions in locally convex spaces.
