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.
