Nonlinear Differential Equations

Non-Linear Differential Equations covers the general theorems, principles, solutions, and applications of non-linear differential equations.
This book is divided into nine chapters. The first chapters contain detailed analysis of the phase portrait of two-dimensional autonomous systems. The succeeding chapters deal with the qualitative methods for the discovery of periodic solutions in periodic systems. The remaining chapters describe a synthetical approach to the study of asymptotic properties, especially stability properties, of the solutions of general n-dimensional systems.
This book will be of great value to mathematicians, researchers, and students.
