Hyers-Ulam-Rassias Stability for a First Order Functional Differential Equation

Cemil Tunç, Emel Biçer


In this paper, by using the fixed point method, we prove two new results on the Hyers-Ulam-Rassias and the Hyers-Ulam stability for the first order delay differential equation of the form

y′(t) = F(t, y(t), y(t −τ )).

Our results improve some related results in the literature.
