“Margulis is one of the great mathematicians of the twentieth century and the first decades of this century, whose work is central today. This valuable book collects reflections on his work by some of the most prominent scholars in the area. Uniquely broad in scope, the whole collection is very strong, and the whole is greater than the parts. Terrific!”

— Shmuel Weinberger, University of Chicago

“A superb contribution in every regard: purely scientifically; expounding upon the many deep works of Margulis and thereby appropriately honoring him and his work; and putting the contributions in context and sorting them in appropriate categories, while explaining the deep connections between them. The intellectual level of this book is astounding. I will recommend it to all my associates, graduate students, postdocs, and other researchers, and surely to my library.”

— Ralf Spatzier, University of Michigan

“Margulis’s work has had a tremendous impact on mathematics, and this book will be read by scholars from a broad cross-section of mathematical backgrounds connected to the four sections of the volume and beyond. It will serve as a go-to collection for specialists and graduate students alike.”

— Alan Reid, Rice University

"Margulis is without a doubt one of the most influential mathematicians of the past fifty years. The book

*Dynamics, Geometry, Number Theory* is vast in scope and provides an excellent introduction to Margulis's work and the research that it has inspired. It will be of great interest not only to specialists, but to graduate students and researchers interested in ergodic theory, Lie theory, geometry, and number theory."

— MAA Reviews

"The chapters have all been written by the foremost experts on each topic with a view to making them accessible both to graduate students and to experts in other parts of mathematics. This was no simple feat: Margulis’s work stands out in part because of its depth, but also because it brings together ideas from different areas of mathematics. Few can be experts in all of these fields, and this diversity of ideas can make it challenging to enter Margulis’s area of research. *Dynamics, Geometry, Number Theory* provides one remedy to that challenge."
