Fascinating connections exist between group theory and automata theory, and a wide variety of them are discussed in this text. Automata can be used in group theory to encode complexity, to represent aspects of underlying geometry on a space on which a group acts, and to provide efficient algorithms for practical computation. There are also many applications in geometric group theory. The authors provide background material in each of these related areas, as well as exploring the connections along a number of strands that lead to the forefront of current research in geometric group theory. Examples studied in detail include hyperbolic groups, Euclidean groups, braid groups, Coxeter groups, Artin groups, and automata groups such as the Grigorchuk group. This book will be a convenient reference point for established mathematicians who need to understand background material for applications, and can serve as a textbook for research students in (geometric) group theory.

A tribute to an extraordinary landscape now under severe threat. The exquisite photographs reveal the mountain ash forests of central Victoria to be one of Australia's great natural treasures. The city of Melbourne lies on the edge of a vast plain surrounded by a green and blue mountainous rim, whose hills and peaks are home to the magnificent Mountain Ash, the tallest flowering plant on the planet. The Mountain Ash forests were 20 million years in the making, and deep within the valleys are even more ancient, Gondwanic rainforests. The Great Forest showcases these forests as well as the world's tallest moss, breathtaking snow gum plateaus and the remnants of massive extinct volcanoes. The Great Forest is a tribute to extraordinary landscapes now under severe threat from logging and wildfires, such as the catastrophic fire that struck on Black Saturday in 2009. It uncovers the intricate webs of life that make Mountain Ash forests so much more than their towering trees. It explores the unique forests that have sustained the Gunaikurnai, Taungurung and Wurundjeri peoples for tens of thousands of years, and that provide a home for creatures found almost nowhere else. The exquisite photographs reveal the Central Highlands of Victoria to be one of Australia's largely undiscovered natural treasures. 'With its glorious photographs, The Great Forest shows why these forests must be preserved for future generations.' - Tim Flannery 'The Great Forest shows the incredible beauty, wonder and value of this amazing part of Victoria.' - David Pocock 'It's rare to read a book that fills your heart with joy and your eyes with tears, all at the same time. The Great Forest does just this.' - Sophie Cunningham 'This wonderful new book highlights the magnificent wet forests of Victoria, and why it is so critical to protect them for their biodiversity, their beauty, and for all of humanity.' - Dame Jane Goodall
