The dependence of local regularity of solutions on the summability of coefficients and nonhomogenous term

Zheng Li Bin Guo

In this paper, we mainly discuss the local regularity of the solution to the following problem \begin{align*} \begin{cases} -\dive({\bf{A}}(x)\nabla u(x))=f(x),&~x\inΩ,\\ u(x)=0,&~…
