This volume presents an authoritative, unified overview of the methods and results concerning the global properties of linear differential equations of order n

The book contains seven survey papers about ordinary differential equations.The common feature of all papers consists in the fact that nonlinear equations are f

Today Lie group theoretical approach to differential equations has been extended to new situations and has become applicable to the majority of equations that f

This series aims at reporting new developments of a high mathematical standard and of current interest. Each volume in the series shall be devoted to mathematic
