A class of nonlocal integrodifferential equations via fractional derivative and its mild solutions. (English) Zbl 1235.34210
Summary: We discuss a class of integrodifferential equations with nonlocal conditions via a fractional derivative of the type: \[ \begin{split} D^q_tx(t)= Ax(t)+\int^t_0B(t-s)x(s)ds+t^nf(t,x(t)),\quad t\in [0,T],\;n\in Z^+,\\ q\in(0,1],\;x(0)=g(x)+x_0.\end{split} \] Some sufficient conditions for the existence of a mild solution are given. The main tools are the resolvent operator and fixed point theorems due to Banach’s fixed point theorem, Krasnoselskii’s fixed point theorem and Schaefer’s fixed point theorem. Finally, an example is given.
