摘要

研究了α∈(1,2)$ \alpha \in(1,2)$阶分数阶演化方程解的存在性和Hölder正则性。利用解析解构造插值空间，有效地降低了初始数据的正则性。利用插值空间和解析解的一些性质，导出了一类非齐次问题严格解的存在性和Hölder正则性，以及一类非线性问题严格解的存在性和Hölder正则性。

Existence and regularity of strict solutions for a class of fractional evolution equations

We study the existence and Hölder regularity of solutions for fractional evolution equations of order $α \in (1, 2)$ . By means of an analytic resolvent, we construct an interpolation space, which can effectively lower the regularity of initial data. By virtue of the interpolation space and some properties of the analytic resolvent, we derive the existence and Hölder regularity of strict solutions for an inhomogeneous problem, as well as the existence and Hölder regularity of a nonlinear problem.
