Title: Generalized Toda and Volterra systems
Abstract:
We define some new, integrable Toda and Volterra type systems. More specifically, we construct a large family of Hamiltonian systems which interpolate between the tridiagonal and full version of the system. In the case of Toda there is one such system for every nilpotent ideal in the Borel subalgebra. In the case of Volterra lattices, the Hamiltonian vector field of the new systems is homogeneous cubic but in a number of cases a simple change of variables transforms such a system to a quadratic Lotka-Volterra system.
