On Besicovitch-Doss almost periodic solutions of abstract Volterra integro-differential equations


Marko Kostić




In this note, we introduce the class of Besicovitch-Doss almost periodic functions in Banach spaces. After that, we investigate Besicovitch-Doss almost periodic properties of finite and infinite convolution products. Our results can be simply incorporated in the qualitative analysis of solutions of certain classes of abstract (degenerate) Volterra integro-differential equations in Banach spaces.
