Abstract
In this paper, we present a new non-overlapping domain decomposition algorithm for the Helmholtz equation. We are particularly interested in the method introduced by P.-L. Lions [6] for the Laplace equation and extended to the Helmholtz equation by B. Després [3]. However, this latest approach provides slow convergence of the iterative method due to the choice of the transmission conditions. Thus, in order to improve the convergence, several methods were developed [4, 5, 9, 10].
