The first edition of this book was the indispensable reference for
researchers in the theory of pro-p groups. In this second edition the
presentation has been improved and important new material has been
added. The first part of the book is group-theoretic. It develops the
theory of pro-p groups of finite rank, starting from first principles
and using elementary methods. Part II introduces p-adic analytic groups:
by taking advantage of the theory developed in Part I, it is possible to
define these, and derive all the main results of p-adic Lie theory,
without having to develop any sophisticated analytic machinery. Part
III, consisting of new material, takes the theory further. Among those
topics discussed are the theory of pro-p groups of finite coclass, the
dimension subgroup series, and its associated graded Lie algebra. The
final chapter sketches a theory of analytic groups over pro-p rings
other than the p-adic integers.
