Positive Poisson integrators for approximating Lotka-Volterra predator-prey model will be described. They are based on the trasformatin of the systems into the field of positive solutions by means of a log transformation.

Abstract
Positive Poisson integrators for approximating Lotka-Volterra predator-prey model will be described. They are based on the trasformatin of the systems into the field of positive solutions by means of a log transformation. Splitting and composition schemes for positive approximation of population dynamics with prey logistic growth and Holling II type functional response will be also introduced.File in questo prodotto:
