Electric Impedance Tomography problem for surfaces with internal holes

A. V. Badanin, M. I. Belishev, D. V. Korikov

Let $(M, g)$ be a smooth compact Riemann surface with the multicomponent boundary $Γ = Γ_{0} \cup Γ_{1} \cup \dots \cup Γ_{m} =: Γ_{0} \cup Γ ~$ . Let $u = u^{f}$ obey $Δ u = 0$ in $M$ , $u|_{Γ_0}=f,\,\,u|_…

The Lyapunov function for Schrödinger operators with a periodic 2x2 matrix potential

Andrei Badanin, Jochen Brüning, Evgeny Korotyaev

We consider the Schrödinger operator on the real line with a 2x2 matrix valued 1-periodic potential. The spectrum of this operator is absolutely continuous and consists of interval…

Spectral asymptotics for periodic fourth order operators

Andrei Badanin, Evgeny Korotyaev

We consider the operator $d^{4} d t^{4} + V$ on the real line with a real periodic potential $V$ . The spectrum of this operator is absolutely continuous and consists of intervals separat…
