Let H =&( 2 Â2) 2+V(x) be a Schro dinger operator on R n , with smooth potential V(x) Ä + as |x| Ä + . The spectrum of H is discrete, and one can study the asymptotic of the smoothed spectral density We shall investigate the case where E is a critical value of the symbol H of H and, extending the w

✦ Synopsis
We prove multidimensional analogs of the trace formula obtained previously for one-dimensional Schro dinger operators. For example, let V be a continuous function on [0, 1] & /R & . For A/[1, ..., &], let &2 A be the Laplace operator on [0, 1] & with mixed Dirichlet Neumann boundary conditions .(x)=0, x j =0 or x j =1 for j # A, .
x j (x)=0, x j =0 or x j =1 for j  A.

Our goal is to show that large classes of Schro dinger operators H=&2+V in L 2 (R d ) exhibit intervals of dense pure point spectrum, in any dimension d. We approach this by assuming that the potential V(x) coincides with a potential V 0 (x) of a ``comparison operator'' H 0 =&2+V 0 on a sequence of
