Burger, Marc Estimation de petites valeurs propres du laplacien d’un revêtement de variétés riemanniennes compactes. (Estimation of small eigenvalues of the Laplacian of a covering of compact Riemannian manifolds). (French) Zbl 0585.53035 C. R. Acad. Sci., Paris, Sér. I 302, 191-194 (1986). Summary: We give lower bounds for the small eigenvalues of the Laplacian of a covering M’\(\to M\) of compact Riemannian manifolds in terms of the spectrum of an associated graph.
