CoordenaÃÃo de AperfeÃoamento de Pessoal de NÃvel Superior / FundaÃÃo Cearense de Apoio ao Desenvolvimento Cientifico e TecnolÃgico / Neste texto, serà apresentado um resultado proposto por Paulo Cordaro e Jorge Hounie sobre o decaimente do primeiro autovalor do operador de Laplace-Beltrami em uma superfÃcie de nÃvel conexa em Sn+1, n ≥1. Esta dissertaÃÃo baseia-se no artigo "The First Eingenvalue of Analytic Level Surfaces on Spheres"de Sagun Chanillo (Mathematical Reseach Letters, vol 1 (1994), p. 159-166). / In the text, will presented one resultad proposed by Paulo Cordaro and Jorge Hounie concerning the possible rate of decay of the first eigenvalue of Laplace-Beltrami operator on a level surface connected in Sn+1, n ≥ 1 This thesis is basead on the paper "The First Eingenvalue of Analytic Level Surfaces on Spheres"of Sagun Chanillo (Mathematical Reseach Letters, vol. 1 (1994), p. 159-166).
