Introduction to Approximate Groups

‘The book now under reviews offers an excellent introduction … the book is very nicely written, Researchers and fledgling researchers in this area will want to own this book.’ Mark Hunacek, The Mathematical Gazette‘… an aspiring student who wants to enter the world of approximate groups will surely find the first chapters of the book, which cover the fundamentals, invaluable. Moreover, anyone willing to climb the mountain that is the BGT theorem should be grateful for the webbing ladders laid out in Chapters IV–VI. Less ambitious readers might still enjoy the small gems, scattered throughout the text, like Solymosi’s sum-product theorem in Chapter IX or the Sanders–Croot–Sisask power set argument in Chapter X, both of which are a delight to read… this is perhaps the first book that provides a systematic treatment of approximate groups as a mathematical subject. It is very likely to become one of standard texts in this rapidly developing field.’ Michael Bjorklund, Bulletin of the American Mathematical Society

Matthew C. H. Tointon is the Stokes Research Fellow at Pembroke College, Cambridge, affiliated to the Department of Pure Mathematics and Mathematical Statistics at the University of Cambridge. He has held postdoctoral positions at Homerton College, Cambridge, at the Université de Paris-Sud and at the Université de Neuchâtel, Switzerland. Tointon is the author of numerous research papers on approximate groups and he proved the strongest known results describing the structure of nilpotent and residually nilpotent approximate groups.
