Abstract: The problem considered here is that of describing generically the zeros, critical points and critical values of eigenfunctions of elliptic partial differential operators. We consider operators of the form $ L + \rho $, where L is a fixed, second-order, selfadjoint, $ {C^\infty }$ linear elliptic partial differential operator on a compact manifold (without boundary) and $ \rho $ is a $ {C^\infty }$ function. It is shown that, for almost all $ \rho $, i.e. for a residual set, the eigenvalues of $ L + \rho $ are simple and the eigenfunctions have the following properties: (1) they are Morse functions; (2) distinct critical points have distinct critical values; (3) 0 is not a critical value.
