On the equivalence of different Lax pairs for the Kac-van Moerbeke hierarchy
J. Michor and G. Teschl
Keywords: Kac-van Moerbeke hierarchy, Lax pair, Toda hierarchy.
Abstract: We give a simple algebraic proof that the two different Lax pairs for the Kac-van Moerbeke hierarchy, constructed from Jacobi respectively super-symmetric Dirac-type difference operators, give rise to the same hierarchy of evolution equations. As a byproduct we obtain some new recursions for computing these equations.
