Abstract
Existence of solutions of a functional differential equation where
the sate depends on its derivative will be studied. Uniqueness of
the solution will be analyzed and continuous dependence of the
unique solution will be proved. Some examples will be given.
Буде вивчено існування розв'язків
функціонально-диференціального рівняння, стан якого залежить від
його похідної. Буде проаналізована єдиність розв'язку і доведено
неперервну залежність єдиного розв'язку. Наведені деякі приклади.
Key words: Functional equations, sate–dependent, existence of solutions, continuous solutions, continuous dependence.
