P. Bueken, MULTI-HAMILTONIAN STRUCTURES FOR A CLASS OF DEGENERATE COMPLETELY INTEGRABLE SYSTEMS, Journal of mathematical physics, 37(6), 1996, pp. 2851-2862
In this paper, a class of degenerate (i.e., associated to a degenerate
Poisson structure) completely integrable systems is studied which gen
eralizes the so-called odd and even master systems introduced and stud
ied by Mumford and by Vanhaecke. It is shown that all these completely
integrable systems, called the generalized master systems, admit a mu
lti-Hamiltonian formulation, and a systematic construction of this mul
ti-Hamiltonian structure is described. (C) 1996 American Institute of
