摘要: In this talk, we present our recent studies on the stability of viscous shocks to Burgers equations with fast diffusion and singularity. When the constant state u+=0, Burgers equations possess a strong singularity due to the fast diffusion in porous media. In order to overcome this singularity, we adopt the technical weighted-energy method, where the weights are carefully selected, which are related to the viscous shocks. A number of numerical simulations are also carried out, which show that the shape of solution becomes steeper as the effect of fast diffusion is more strong.
