Recurrent Sequences

Dorin Andrica is a Professor of Mathematics at the Babeș-Bolyai University of Cluj Napoca, Romania. He has obtained a PhD in Pure Mathematics in 1992 with a thesis on critical point theory with applications to the geometry of differentiable submanifolds. His interests include differential topology (critical point theory with applications, Morse theory with applications), differential geometry,  geometry, Lie groups and Lie algebras with applications in geometric mechanics, number theory, discrete mathematics, and mathematics for competitions. Dorin has co-authored Springer textbooks on various topics in mathematics, as well as problem books for olympiad training.  Ovidiu Bagdasar is an Associate Professor in Mathematics at the University of Derby, United Kingdom. He holds PhDs in Applied Mathematics (University of Nottingham, 2011), and Pure Mathematics (Babeș-Bolyai University,  2015), the latter with a thesis entitled "On the geometry and applications of complex recurrent sequences".   His research is at the boundary between Mathematics and Computer Science, encompassing areas like number theory, optimization, computational, discrete and applied mathematics. He is the author of the SpringerBriefs volume Concise Computer Mathematics Tutorials on Theory and Problems.

“What a delightful, current, compactly written book. This book could serve as a stand-alone text i) for an advanced, undergraduate, second-term, Discrete-Mathematics course, ii) for a first, or preferably, second-year stand-alone text for graduate students specializing in dynamical systems, combinatorics, or discrete systems, or iii) for researchers in these areas. … The book presents close to 200 references most of which are post-2000. Anyone wanting to read further will find what they need here.” (Russel Jay Hendel, MAA Reviews, April 10, 2022)“This book teaches numerous fundamental facts and techniques which are central in mathematics. It is both a research monograph and a delightful problem book, which I feel will spark the interest of a wide audience, from mathematics Olympiad competitors and their coaches to undergraduate or postgraduate students, or professional mathematicians with an interest in recurrences and their multiple applications.” (Michael Th. Rassias, EMS Magazine, Issue 119, March, 2021)
