We consider metric graphs which consist of a finite graph with half-infinite leads attached to some of the vertices. To this graph is associated a Laplacian using the Kirchhoff boundary conditions. We describe some asymptotic properties of the resonances close to the real axis.

This is a joint work with Y. Colin de Verdière.
