Borne explicit du nombre de tores plats isospectraux à un tore donné. (Explicit bound of the number of flat tori isospectral to a given flat torus)
The author gives an explicit bound of the number of isometry classes of flat \(n\)-dimensional tori isospectral to a given flat \(n\)-dimensional torus. The bound is expressed only in geometrical terms. In the particular case \(n=3\) the author proves that there exist 3612 of such classes.
