Multidimensional periodic and almost-periodic problems.
GAMP seminar
Speaker: Leonid Parnovski, UCL, London
Abstract: I will make a survey of the recent developments in the spectral theory of multidimensional periodic and almost-periodic differential operators, concentrating mostly on Schroedinger type operators. In particular, I will discuss the Bethe-Sommerfeld Conjecture and the asymptotic expansion of the Integrated Density of States and other spectral characteristics.
