This book examines the main theorems in bifurcation theory. It covers both the local and global theory of one-parameter bifurcations for operators acting in infinite-dimensional Banach spaces and shows how to apply the theory.

In the past three decades, bifurcation theory has matured into a well-established and vibrant branch of mathematics. This book gives a unified presentation in an abstract setting of the main theorems in bifurcation theory, as well as more recent and lesser known results. It covers both the local and global theory of one-parameter bifurcations for operators acting in infinite-dimensional Banach spaces, and shows how to apply the theory to problems involving partial differential equations. In addition to existence, qualitative properties such as stability and nodal structure of bifurcating solutions are treated in depth. This volume will serve as an important reference for mathematicians, physicists, and theoretically-inclined engineers working in bifurcation theory and its applications to partial differential equations.

The second edition is substantially and formally revised and new material is added. Among this is bifurcation with a two-dimensional kernel with applications, the buckling of the Euler rod, the appearance of Taylor vortices, the singular limit process of the Cahn-Hilliard model, and an application of this method to more complicated nonconvex variational problems.

From the reviews of the second edition:

"This book is a valuable resource for mathematicians working in the areas of Nonlinear Analysis and/or Differential Equations. ... This book is intended for advanced graduate students, for specialists in Bifurcation Theory and for researchers in related areas willing to master the subject. ... this is a great reference book on the subject of Bifurcations." (Florin Catrina, MAA Reviews, January, 2013)

"The volume under review gives a unified presentation in an abstract setting of the main theorems in bifurcation theory, in relation with some new results and relevant applications to partial differential equations. ... The book is very well written and the many examples make it an excellent choice for a good course on bifurcation problems." (Vicentiu D. Radulescu, Zentralblatt MATH, Vol. 1230, 2012)
