From the reviews: "This monograph written by excellent specialists in the fundamental theory of limit cycles represents an introduction to the most new developments and systematical presentation of major advances in this field which come mainly from the authors' own recent research results. ... Classic topics with recent results are presented in a clear and concise manner that will be suitable for post-graduate students studying the theory of limit cycles as well as for scientists interesting in the applications of periodic behavior." (Alexander Grin, Zentralblatt MATH, Vol. 1252, 2012) "This excellent book advances the theory of Limit Cycles-isolated periodic orbits that are sometimes referred to as self-sustained oscillations in the literature. ... This book stands out with worked-out examples galore and efficient and accessible algorithms on classical subjects ... . The authors aim at shedding new light on 'old' settled results as well as introducing recent advances in the field. The book achieves both handsomely, through a highly readable and convincing exposition that harnesses the power of modern computational tools ... ." (Bourama Toni, Mathematical Reviews, January, 2013)
