演讲主题：Linear and Nonlinear Waves in Multidimensional Gas Dynamics Equations 

地点：环境学院316房间 报告摘要：As the community of analysts studying hyperbolic conservation laws continues to
make progress on multidimensional problems, largely through the study of
self-similar solutions to shock reflection phenomena, one difficulty that
emerges is the interaction of nonlinear waves (such as acoustic waves in
compressible flow) and linear waves (shear or entropy waves, for example). In
recent work with Katarina Jegdic, Suncica Canic and Hao Ying, we have developed
an approach that solves a small, local problem.
