摘要
该文利用非紧性测度、β-预解族、k-集压缩原理研究了一类混合型分数阶半线性积分-微分方程温和解的存在性.众所周知,利用k-集压缩原理证明解的存在性时需要单独给出附加条件来保证压缩系数小于1,而该文不需要单独附加保证压缩系数小于1的条件.在更一般的条件下证明了方程解的存在性.文章最后给出了一个例子说明该文主要结果的应用.
In this paper,the authors studied the existence results of the mild solutions for a class of fractional semilinear integro-differential equation of mixed type by using the measure of noncompactness,k-set contraction andβ-resolvent family.It is well known that the k-set contraction requires additional condition to ensure the contraction coefficient 0<k<1.We don’t require additional condition to ensure the contraction coefficient 0<k<1.An example is introduced to illustrate the main results of this paper.
