On various integrable discretisations of a general two component Volterra system
Published 19 Aug 2015 in nlin.SI | (1508.04661v1)
Abstract: We present two integrable discretisations of a general differential-difference bicomponent Volterra system. The results are obtained by discretising directly the corresponding Hirota bilinear equations in two different ways. Multisoliton solutions are presented together with a new discrete form of Lotka-Volterra equation obtained by an alternative bilinearisation.
