Qualitative features of periodic solutions of KdV
T. Kappeler, B. Schaad, P. Topalov
In this paper we prove new qualitative features of solutions of KdV on the circle. The first result says that the Fourier coefficients of a solution of KdV in Sobolev space $H^N,\,…

Asymptotics of spectral quantities of Schrödinger operators
T. Kappeler, B. Schaad, P. Topalov
In this paper we provide new asymptotic estimates of the Floquet exponents of Schrödinger operators on the circle. By the same techniques, known asymptotic estimates of various oth…
