Polynomial Methods and Incidence Theory
Polynomial Methods and Incidence Theory
The past decade has seen numerous major mathematical breakthroughs for topics such as the finite field Kakeya conjecture, the cap set conjecture, Erdős's distinct distances problem, the joints problem, as well as others, thanks to the introduction of new polynomial methods. There has also been significant progress on a variety of problems from additive combinatorics, discrete geometry, and more. This book gives a detailed yet accessible introduction to these new polynomial methods and their applications, with a focus on incidence theory. Based on the author's own teaching experience, the text requires a minimal background, allowing graduate and advanced undergraduate students to get to grips with an active and exciting research front. The techniques are presented gradually and in detail, with many examples, warm-up proofs, and exercises included. An appendix provides a quick reminder of basic results and ideas.
- Requires a minimal background and includes numerous examples, warm-up proofs, figures, and intuitive ways of thinking about complex ideas
- Contains over 100 exercises that can be used by instructors in courses or by readers for extra practice
- Discusses the main open problems in polynomial methods and incidence theory to encourage further research
Reviews & endorsements
'This book gives a very nice introduction to the areas of incidence geometry and the polynomial method … Since this area of mathematics is still rather young, the book contains many open problems - this helps to bring the reader to the front of research. Furthermore, each chapter is followed by a generous amount of exercises.' Audie Warren, zbMATH Open
