?MIXED MONO TONICITY THEOREMS FOR A SYSTEM OF ABSTRACT MEASURE DELAY INTEGRO-DIFFERENTIAL EQUATIONS

Abstract

In this paper the existence of extremal solutions of a system of nonlinear abstract measure delay integra-differential
equations is established using the fixed point theorem of Tar ski. Two basic integra-differential inequalities are obtained
which are further applied to prove the boundedness and uniqueness of the solution of related abstract measure delay
integra-differential equations.
