We build new examples of extremal domains with small prescribed volume for the first eigenvalue ofthe Laplace-Beltrami operator in some Riemannian manifold with boundary. These domains are close to half ballsof small radius centered at a nondegenerate critical point of the mean curvature function of the boundary of themanifold, and their boundary intersects the boundary of the manifold orthogonally.Subjects / Keywords
