Abstract
In this paper we consider the initial-boundary value problems for a class of general singularly perturbed delay reaction diffusion equations which are often met in applications, such as biomathematics and biochemistry. Applying the method of composite expansion we construct the formally asymptotic solution of the problem described. With the help of theory of upper and lower solutions we prove the uniformly validity of the formal solution and the existence of solution of the original problem.
