题目:1Long-time existence of nonlinear inhomogeneous compressible

elastic waves

时间:929 1000-1100

地点:16-416

主讲人:尹思露

 

摘要:In this talk, we consider the nonlinear inhomogeneous compressible elastic waves in three spatial dimensions when the density is a small disturbance around a constant state. In homogeneous case, the almost global existence was established by Klainerman-Sideris, and global existence was built by Agemi and Sideris independently. Here we establish the corresponding almost global and global existence theory in the inhomogeneous case.

题目:2Global existence of inhomogeneous incompressible isotropic elastodynamics in three dimensions

时间:930 1000-1100

地点:16-416

主讲人:尹思露

  

摘要:This talk concerns the Cauchy problem of the incompressible isotropic elas-

todynamics in three dimensions. The homogeneous case was studied by Sideris

and Thomases in Euler coordinates. Here we generalize their result to

the inhomogeneous case and prove the global existence of classical solution in

Lagrangian coordinates under the assumption that the density is a small per-

turbation around a constant state. The generalized energy method is utilized to

derive the energy estimates in certain weighted Sobolev spaces.
