This book is about the interplay between algebraic topology and the theory of infinite discrete groups. It is a hugely important contribution to the field of to

Eminent mathematicians have presented papers on homological and combinatorial techniques in group theory. The lectures are aimed at presenting in a unified way

Aimed at graduate students in physics and mathematics, this book provides an introduction to recent developments in several active topics at the interface betwe

Extensive development of such topics as elementary combinatorial techniques, Sperner's Lemma, the Brouwer Fixed Point Theorem, and the Stone-Weierstrass Theorem

Symmetry has a strong impact on the number and shape of solutions to variational problems. This has been observed, for instance, in the search for periodic solu
