利用Hausdorff非紧性测度理论和Darbo不动点定理,在较弱的条件下得到Banach空间中一类非线性无穷时滞分数阶微分方程解的存在性结果,改进和推广了已有的相关结果.
This paper is concerned with a class of nonlinear fractional differential equanons with infinite delay in Banach spaces. Using the theory of Hausdorff measure of noncompactness and Darbos fixed point theorem, the existence of mild solutions is obtained, which improves and extends some previous results.
