# 应数学与统计学院耿俊教授和杨四辈教授邀请,中国矿业大学(北京)张俊强博士将于2020年12月27日-30日访问兰州大学并于12月28日下午作学术报告， 欢迎全校师生参加.

Let w be a Muckenhoupt weight and$\Omega$a Reifenberg flat domain inRn. Assume that$0<q\le\infty$and$1<p(\cdot)<\infty$is a variable exponent satisfying the log-Hölder continuous condition. In this talk, we investigate the weighted variable Lorentz$L^{p(\cdot)},q}(\Omega,w)$ regularity of the weak solutions of second order degenerate elliptic equations in divergence form with Dirichlet boundary condition, under the assumption that the degenerate coefficients belong to weighted BMO spaces with small norms.
