The three common features exhibited by both natural and technological processes are nonlinearity, bifurcation and chaos theory. Floquet exponents and bifurcations in switched converters, dynamics of a pendulum of variable length, mathematical modeling, and non-linearity in structural dynamics are some of the significant concepts in this area of study. The mathematical study of changes in the qualitative structure of a given family and solutions of family of differential equations is referred as bifurcation theory. The branch of mathematics which deals with the study of chaos in dynamical systems where the irregularities and random states of disorder are governed by underlying patterns and deterministic laws is termed as chaos theory. The book presents researches and studies performed by experts across the globe. It includes some of the vital pieces of work being conducted across the world, on various topics related to essential elements of nonlinearity, bifurcation and chaos theory. This book is a resource guide for experts as well as students.
