The Weak Solutions to Doubly Nonlinear Diffusion Equation with Convection Term
Authors: ,
Abstract: Consider the following convection diffusion equation
$$ut = div(| ∇u^{m} | ^{p−2} ∇u^{m}) + \sum_{i=1}^{N} \frac{\partial b_{i}(u^{m}, x, t)}{\partial x_{i}}$$, Supposed that $$0 < m < 1, p > 1 + \frac{1}{m}$$, using Moser iteration technique, we get the local bounded properties of the solution of the regularized problem. By the compactness theorem, the existence of the weak solution of the convection diffusion equation itself is obtained.
