報告摘要：
The degenerate set affects the properties of solutions, especially the regularity. We will distinguish two kind of degenerac. If the set has no interior point,then we call the equation is of weakly degenerate type. The degenerate set of the porous medium equation contains one point, and hence is weakly degenerate. However, for the weakly degenerate equation, the set may have infinite points, even with the positive measure. If the degenerate set has interior point, then the equation is called to be strongly degenerate.
