Abstract

The fundamental objective of this project is the introduction of the theory of differential equations with space-time-state dependent arguments by means of the study of abstract neutral explicit differential equations with applications to partial differential equations. This new theory of differential equations will allow the generalization of an extensive literature on different classes of integral and differential equations with temporal delay. Considering the abstract and complex formulation of the neutral problem considered in this project, we note that the ideas and techniques to be developed in this project can be used in the study of ordinary differential equations in finite and infinite dimensional spaces, of different models of neutral differential equations and partial evolution differential equations. Furthermore, this new theory is motivated by different important applications.
