| Abstract: | The authors considered a free boundary problem arised by the unstable infiltration for two immiscible fluids in perpendicular half unbounded porous medium and with two free boundary.The existence and uniqueness of local solution have been obtained.Now the authors obtain the existence and regularity of the global solution. |
