Burger, Marc; Colbois, Bruno A propos de la multiplicité de la première valeur propre du laplacien d’une surface de Riemann. (On the multiplicity of the first eigenvalue of the Laplacian on a Riemann surface). (French) Zbl 0574.53029 C. R. Acad. Sci., Paris, Sér. I 300, 247-249 (1985). We produce examples of Riemann surfaces whose n-first eigenvalues of the Laplacian are of large multiplicity.
