We construct new examples of compact Riemann surfaces which are non isometric but have the same spectrum of the Laplacian. Examples are given for genus and for all . In a second part we give examples of isospectral non isometric surfaces in which are realizable by paper models.
L’article donne de nouveaux exemples de surfaces de Riemann compactes qui sont non isométriques et ont le même spectre du laplacien. Ces exemples sont donnés pour le genre et pour tous les .
Dans une seconde partie nous construisons des surfaces isospectrales plongées dans qui se réalisent par des modèles en papier.
