考虑一类具有Dirichlet边界条件的抛物型方程,其右侧属于L1 + Lp ' (W−1,p ')。利用重整化解的框架证明了a(u,∇u), K(u)和H(∇u)在适当的生长条件和lipschitz型条件下的唯一性结果。
We consider a general class of parabolic equations of the type with Dirichlet boundary conditions and with a right-hand side belonging to L1 + Lp′ (W−1, p′). Using the framework of renormalized solutions we prove uniqueness results under appropriate growth conditions and Lipschitz-type conditions on a(u, ∇u), K(u) and H(∇u).
