报告摘要：

    The system of thermoelasticity, which governs the evolution of thermoelastic nonconductors of heat, allows two types of characteristic discontinuities: thermoelastic vortex sheets for which the tangential velocity can undergo a jump, and thermoelastic contact discontinuities for which the velocity is continuous across the discontinuity interface. In this talk we will present the structural stability results on two-dimensional elastic vortex sheets (joint with R. M. Chen, J. Hu, D. Wang, and D. Yuan) and multi-dimensional thermoelastic contact discontinuities (joint with G.-Q. G. Chen and P. Secchi).
