The KdV Hierarchy and Associated Trace Formulas
Fritz Gesztesy, R. Ratnaseelan, and Gerald Teschl
A natural algebraic approach to the KdV hierarchy and its algebro-geometric finite-gap solutions is developed. In addition, a new derivation of associated higher-order trace formulas in connection with one-dimensional Schrödinger operators is presented.
