Classes of correctly solvability of the Cauchy problem are specified. The theorems of existence of integral manifolds for the linear system of singularly perturbed functional differential equations with time lag on fast and slow variables are proved. Properties of these manifolds are investigated. The mathematical models of ecology-economics balance are constructed and researched. Product Description popup.authors popup.nrat_date 2020-04-02 Close
