Resonances generated by analytic singularities on the density of states measure for perturbed periodic Schrodinger operators. <i>Electronic Journal of Differential Equations, 2006</i>(60), pp. 1-11.1072-6691https://hdl.handle.net/10877/13933We consider a perturbation of a periodic Shrödinger operator P0 by a potential W(hx), (h ↘ 0). We study singularities of the density of states measure and we obtain lower bound for the counting function of resonances.Text11 pages1 file (.pdf)enAttribution 4.0 InternationalResonancesPerturbationsPeriodic Schrodinger operatorsArticle
