## Optimal three-ball inequalities and quantitative uniqueness for the Lamé system with Lipschitz coefficients.(English)Zbl 1202.35325

Summary: We study the local behavior of a solution to the Lamé system with Lipschitz coefficients in dimension $$n\geq 2$$. Our main result is the bound on the vanishing order of a nontrivial solution, which immediately implies the strong unique continuation property (SUCP). We solve the open problem of the SUCP for the Lamé system with Lipschitz coefficients in any dimension.
