Abstract:
We study the evolution p-Laplacian equation with the nonlinear
gradient term
where
, p>1 and p>q>0.
When a(x)>0 and B(x)>0, the uniqueness of weak solution to this equation
may not be true. In this study, under the assumptions that the diffusion
coefficient a(x) and the damping coefficient B(x) are degenerate on
the boundary, we explore not only the existence of weak solution,
but also the uniqueness of weak solutions without any boundary value condition.
