“…Over many years these systems have been used in many branches of sciences like laser physics [27], neural networks [40], plasma physics [28], chemical kinetics [39], etc. The dynamical behaviour of these models has been widely studied, see for instance [1,14,8,45,49,34] among others. The integrability of some Lotka-Voltera families was considered by several authors, see for example [15,16,18,31,34,36].…”
