# PDF Introduction to the theory of functional differential equations

Therefore, one can conclude that. That is,. This fact shows that all solutions of the equation considered are bounded.

We establish the following result. Then, there exists a finite positive constant K such that the solution x t of equation 1 defined by the initial functions. Now, in view of 4 , it follows that. Now, the estimates related to V 1 and V 2 yield. Now, let. Then, a direct computation along this solution shows that. In view of the assumptions of theorem and expression 5 , we have that.

Making use of these inequalities, we get. Now, subject to the assumptions ii and iii of theorem, one easily finds that. Gathering the above discussion into 8 and making use of the assumption ii , it follows that.

### 1 Introduction

In view of 7 , it follows that. Now, the inequality 7 and the last inequality together give that. This fact completes the proof of theorem.
