| Abstract: | In this paper,the regularity of the weak solution to the initial value problem for second-order elliptic equations Lu=f in U under some conditions assumptions was discussed.Through some techniques and methods,the interior regularity of the weak solution was described.These techniques and methods include cut off function,flatten out the boundary,finitely covered theorem,sobolev inequalities,interpolation inequalities,etc. |
