The aim of this works is to show superior estimatives to the least non-zero eingenvalue lambda1 of the Laplace-Beltrami operator delta. The forthcoming results were discovered by Reilly [1] and the duo A. El Soufi and S. Ilias [2]. Reilly’s Estimative was calculated for immersed manifolds in the Euclidian Space Rn, and Soufi-Ilias for conformally immersed manifolds in the sphere Sn.Then, we conclude the result, again by Soufi-Ilias [2], for submanifolds of the hyperbolic space Hn.O objetivo desse trabalho é mostrar estimativas superiores para o menor autovalor não-nulo lambda1 do operador de Laplace-Beltrami delta. Os resultados que se seguem foram encontrados por R. Reilly [1] e a dupla A. El Soufi e S. Ilias [2]. A estimativa de Reilly é ...
