报告摘要：We will discuss the incompressible limit of compressible dissipative elastodynamics when the shear viscosity converges to zero in dimension two. The incompressible limit is characterized by the large value of the volume viscosity. In the limit, the dispersive effect of pressure waves disappears and the global convergence to the limit system around an equilibrium is justified with the help of vector fields and the ghost weight method. This is a joint work with Xiufang Cui.
