By the assumption of that a(x)|∇u| p ≤ c, a(x)|∇v| p ≤ c, using the Young inequality
This paper is mainly about the infiltration equation u t = div ( a ( x ) | u | α | ∇ u | p − 2 ∇ u ) , ( x , t ) ∈ Ω × ( 0 , T ) , $$ {u_{t}}= \operatorname{div} \bigl(a(x)|u|^{\alpha }{ \vert { \nabla u} \vert ^{p-2}}\nabla u\bigr),\quad (x,t) \in \Omega \times (0,T), $$ where p > 1 $p>1$ , α > 0 $\alpha >0$ , a ( x ) ∈ C 1 ( Ω ‾ ) $a(x)\in C^{1}(\overline{\Omega })$ , a ( x ) ≥ 0 $a(x)\geq 0$ with a ( x ) | x ∈ ∂ Ω = 0 $a(x)|_{x\in \partial \Omega }=0$ . If there is a constant β $\beta $ such that ∫ Ω a − β ( x ) d x ≤ c $\int_{\Omega }a^{-\beta }(x)dx\leq c$ , p > 1 + 1 β $p>1+\frac{1}{\beta }$ , then the weak solution is smooth enough to define the trace on the boundary, the stability of the weak solutions can be proved as usual. Meanwhile, if for any β > 1 p − 1 $\beta >\frac{1}{p-1}$ , ∫ Ω a − β ( x ) d x d t = ∞ $\int_{\Omega }a^{-\beta }(x)dxdt=\infty $ , then the weak solution lacks the regularity to define the trace on the boundary. The main innovation of this paper is to introduce a new kind of the weak solutions. By these new definitions of the weak solutions, one can study the stability of the weak solutions without any boundary value condition.
