| 摘 要： | Infiltration problem with two kinds of degenerate cases is considered.After proving the existenceof weak solution,we study when water content c(u(·,t))has compact support and how the solutionbehaves as t→∞.Moreover,we get existence and regularity of two kinds of free boundaries undersome conditions on the initial date. |
