Linear differential equations. Classical and modern theory

The present book is devoted to methods of integration of differential equations from the classical point of view as well as by means of distributions theory. One points out the practical origins and applications of these functional equations illustrating them by examples from physics biology medicine. The corresponding solutions are given. Notions of wronskian delta-distribution and their applications as well as the stability of equilibrium points play a central role. The book contains some of the original results of the first author presented in over eight international conferences. Equations with singularities are also studied. This work is useful to high level students Master students professors engineers and any reader interested in the field.
