This book provides a crash course on various methods from the bifurcation theory of Functional
Differential Equations (FDEs). FDEs arise very naturally in economics life sciences and
engineering and the study of FDEs has been a major source of inspiration for advancement in
nonlinear analysis and infinite dimensional dynamical systems. The book summarizes some
practical and general approaches and frameworks for the investigation of bifurcation phenomena
of FDEs depending on parameters with chap. This well illustrated book aims to be self contained
so the readers will find in this book all relevant materials in bifurcation dynamical systems
with symmetry functional differential equations normal forms and center manifold reduction.
This material was used in graduate courses on functional differential equations at Hunan
University (China) and York University (Canada).
