Resonances generated by analytic singularities on the density of states measure for perturbed periodic Schrodinger operators
We consider a perturbation of a periodic Shrodinger operator $P_0$ by a potential $W(hx)$, $(hsearrow 0)$. We study singularities of the density of states measure and we obtain lower bound for the counting function of resonances.
