English Abstract
Let H_0 = −d^2/dx^2 + V_0 be an infinite band Schrödinger operator on L^2(R) with a real-valued potential V_0 ∈ L^\infty (R). We study its complex perturbation H = H_0+V , defined in the form sense, and obtain the Lieb-Thirring ...Read more >
Let H_0 = −d^2/dx^2 + V_0 be an infinite band Schrödinger operator on L^2(R) with a real-valued potential V_0 ∈ L^\infty (R). We study its complex perturbation H = H_0+V , defined in the form sense, and obtain the Lieb-Thirring type inequalities for the rate of convergence of the discrete spectrum of H to the joint essential spectrum. The assumptions on V vary depending on the sign of Re V .Read less <
