Strong unique continuation for the Lamé system with Lipschitz coefficients in three dimensions*
Published online by Cambridge University Press: 23 April 2010
Abstract
This paper studies the strong unique continuation property for the
Lamé system of elasticity with variable Lamé coefficients
λ, µ in three dimensions, ${\rm{div}}(\mu(\nabla u+\nabla
u^t))+ \nabla(\lambda{\rm{div}} u)+Vu=0$
where λ and μ are Lipschitz continuous and V∈L∞. The method is based on the Carleman estimate with polynomial weights for the Lamé operator.
