Abstract
We study the first boundary value problem for a class of nonlinear
degenerate parabolic equations −∂u/∂t=div(A→(∇u)). We first consider its regularized
problem and establish some estimates. Based on these estimates,
we prove the existence and uniqueness of the generalized
solutions in BV space.
