Measure of Noncompactness and Nondensely Defined Semilinear Functional Differential Equations with Fractional Order

摘要

This paper is devoted to study the existence of integral solutions for a nondensely defined semilinear functional differential equations involving the Riemann-Liouville derivative in a Banach space. The arguments are based upon M?nch’s fixed point theorem and the technique of measures of noncompactness.
