报告摘要:
In this talk, we will study the multi-dimensional scalar conservation law with a source term. Generally, due to the nonlinearity, the solution of conversation law may blowup at finite time even when the initial data is smooth. It is interesting to research the existence of smooth solutions and the basic sturctures for weak solutions. I will present some relative results in these directions as follows: 1) The necessary and sufficient condition of global smooth solutions; 2) The expressions of basic waves for weak solutions, including n-D shock wave and n-D rarefaction wave. This is joint work with Hui Kan, Wei Xiang and Xiaozhou Yang.
