Thomas Kappeler, Yannick Widmer Institut für Mathematik, Universität Zürich, Winterthurerstrasse 190, CH-8057 Zürich, Switzerland
Abstract:
We analyze the periodic spectrum of the $L$ operator in the Lax pair of the sine-Gordon equation in terms of the regularity of the potential.
Key words and phrases:
sine-Gordon equation, sinh-Gordon equation, Lax pair, decay properties of gap lengths.
