A Hidden Connection between Lax Descriptions and Superextensions of KdV Hierarchy
Wen-Jui Huang
Abstract
A previously unnoticed connection between the Lax descriptions and the superextensions of the KdV hierarchy is presented. It is shown that the two different Lax descriptions of the KdV hierarchy come out naturally from two different bihamiltonian superextensions of the KdV hierarchy. Some implications of this observation are briefly mentioned.
