摘要

This paper deals with the derivative with respect to a smooth compact manifold of the solution of equations associated with tangential second order derivative's operators on the manifold. We give a result concerning the shape boundary derivative for the solution of the Laplace Beltrami equation on a manifold whithout boundary. For simplicity we assume the manifolds to be open subsets in the boundary of smooth domains. In a second step we consider a tangential boundary value problem on an open subset ω which has itself a non empty relative boundary on which Dirichlet condition is imposed. Finaly we make use of that result in order to give a result of shape boundary derivative of the solution of an elastic membrane problem.
