Pseudo-almost periodic solutions of neutral integral and differential equations with applications (Q972388)

The concepts of almost periodicity, and pseudo almost periodicity in two variables are introduced. Then, the author studies the existence and uniqueness of almost periodic, and pseudo almost periodic solutions to some popular neutral differential equations using the contraction mapping principle. In the referee's point of view, the results generalize some recent ones. However, the lack of examples of such functions along with the absence of applications of the results obtained may constitute a weakness for this very abstract but interesting paper.
