On a Theorem of Halphen and its Application to Integrable Systems
Fritz Gesztesy, Karl Unterkofler, Rudi Weikard
We extend Halphen's theorem which characterizes the solutions of certain th-order differential equations with rational coefficients and meromorphic fundamental systems to a firs…

An Explicit Characterization of Calogero--Moser Systems
Fritz Gesztesy, Karl Unterkofler, Rudi Weikard
Combining theorems of Halphen, Floquet, and Picard and a Frobenius type analysis, we characterize rational, meromorphic simply periodic, and elliptic KdV potentials. In particular,…

Elliptic Algebro-Geometric Solutions of the KdV and AKNS Hierarchies - An Analytic Approach
Fritz Gesztesy, Rudi Weikard
We provide an overview of elliptic algebro-geometric solutions of the KdV and AKNS hierarchies, with special emphasis on Floquet theoretic and spectral theoretic methods. Our treat…
