摘要
研究了二阶非齐次椭圆方程的障碍问题,给出其很弱解的定义,并利用Hodge分解等工具得到障碍问题很弱解的局部正则性结果.
The obstacle problems for second order degenerate nonhomogeneous elliptic equation is studied and the definition of very weak solutions is given by using tools as Hodge decomposition. The higher integrability of the weak derivatives of the solutions is obtained.
