Abstract

Among other unconventional numerical methods, W. Kahan has suggested a discretization of a simple Lotka-Volterra system with the property that the computed points do not spiral. We explain this behaviour by showing that Kahan's method is symplectic with respect to a noncanonical symplectic structure. © 1994.
