Title: On Spectral Curves of CMC Annuli of Finite Type in S^3

Abstract: We call a cmc immersions of the parabolic annulus into
S^3 to be of finite type, if it has bounded curvature and constant
Hopf differential with respect to the coordinate z in C/Z. Such an
annulus is called Alexandrov embedded, if the immersion extends to
a complete three manifold, whose boundary is the annulus. It is
called mean convex, if the mean curvature with respect to the inner
normal is non-negative. All these annuli are determined by solutions
of the sinh Gordon equation of finite type. The corresponding set of
spectral curves is shown to be connected. It turns to be a two-dimensional
set of spectral curves of genus at most one. The corresponding annuli
are all surfaces of revolution.
