The Dirichlet problem for a class of doubly non1inear degenerate parabolic equations-=is studied in this paper.First We give the definition of BVsolutions, then we consider the regularized problem,make approximate solutions and setup some estimates by skill of BV estimates.On the basis of these estimates,We finallyproxre the existence and the uniqueness of global solutions in BV space.

Keywords/Search Tags:
