Preservation of the invariants of Lotka-Volterra equations by iterated deferred correction methods
(Işık University Press, 2021)In this paper we apply Kahan’s nonstandard discretization to three dimensional Lotka-Volterra equations in bi-Hamiltonian form. The periodicity of the solutions and all polynomial and non-polynomial invariants are well ...
