A Homotopy Technique for a Linear Generalization of Volterra ModelsThe classical Lotka-Volterra models from papulation dynamics have the structure of the system of O.D.E..Math where . = }1,2,…,n} is the set of all the indices of the variables, e., a., i,j ∈ . are suitable real parameters and x. = x.(t) represents the density or the biomass of i-th species at time t.
