报告摘要：The research of  multi-dimensional shock wave and  rarefaction wave is difficult and important problem, such as the  constuctions and expression of multi-dimensional shock wave and  rarefaction wave.In this talk, I will introduce how to construct  non-selfsimilar multi-dimensional shock wave and  rarefaction wave and what their expressions are? and will also discuss the uniqueness, the geometric strctures of these two kinds of waves,  and how to apply methods of envelope to investigate the shock wave and rarefaction wave of more complicated type.
