Given a finite sequence of n samples drawn independently at random from a compact submanifold of the Euclidean space, we study the asymptotic behavior of Laplacians on the epsilon-neighborhood graph of this sample set. We show that their eigenvalues and eigenvectors converge to the eigenvalues and eigenfunctions of certain realizations of the Laplace-Beltrami operator as n tends to infinity.
