By using the interior curvature estimate and Gromov's compactness theo
rem, we prove that a stable complete minimal hypersurface in Rn+1 with
finite total scalar curvature must be a hyperplane. This extends the
result obtained by P. Berard in Remarques sur l'equation de J. Simons,
Pitman Monographs Surveys Pure Appl. Math., vol. 52, 1991, pp. 47-57.
