We define and analyze the rotation number for the almost periodic Schrödinger operator L= -d2/dx2+q(x). We use the rotation number to discuss (i) the spectrum of L; (ii) its relation to the Korteweg-de Vries equation.

Abstract
We define and analyze the rotation number for the almost periodic Schrödinger operator L= -d2/dx2+q(x). We use the rotation number to discuss (i) the spectrum of L; (ii) its relation to the Korteweg-de Vries equation.File in questo prodotto:
