Date/Time:02 Oct 2019 16:00Venue: S16 #03-09Speaker: Yin Silu, Hangzhou Normal UniversityGlobal well-posedness of elastodynamicsIn this talk, I will present some classical theory of elastic waves. The motion of elasticity is a wave system with multiple speeds, so Lorentz invariant is absent. For incompressible isotropic elasticity with constant density in 3D, the Cauchy problem with small initial datum were studied by a series work of Sideris and Thomases. We studied the inhomogeneous case in Lagrangian coordinate under the assumption that the density is a small perturbation around a constant state. This is a joint work with Xiufang Cui.Add to calendar:
