Travelling Wave Solutions for Some Degenerate Parabolic Equations ( I )

The existence and regularity of travelling wave front solutions are studied forsome degenerate parabolic equationswith m,n>0 and f satisfies(H):f(u)∈C~10,1],f(0)<0, f(1)<0 and f'(1)<0.There exists a∈(0,1),s.t.f(u)<0 for u∈(0,a) and f(u)>0 for u∈(a,1). A function u=q(z)with z=x+ct is said to be a travelling wave front solution
