Title: Multi-dimensional c-almost periodic type functions and applications Author: Marko Kostic (Univ. of Novi Sad, Serbia) Abstract: In this article, we analyze multi-dimensional Bohr (B,c)-almost periodic type functions. The main structural characterizations for the introduced classes of Bohr (B,c)-almost periodic type functions are established. Several applications of our abstract theoretical results to the abstract Volterra integro-differential equations in Banach spaces are provided, as well. Submitted Janaury 15, 2021.
