TITLE	Uniqueness of Inverse Boundary Value Problem for Dynamical Anisotropic Elasticty Systems
ABSTRACT	We consider the uniqueness of inverse boundary value problem of identifying the elasticity tensors by measurements on the boundary for dynamical anisotropic elastic systems. We assume the tensors are piecewise analytic. We will report several uniqueness results.
