Combinatorics, Complexity and Chance. A Tribute to Dominic Welsh.

Professor Dominic Welsh has made significant contributions to the fields of combinatorics and discrete probability, including matroids, complexity, and percolation, and has taught, influenced and inspired generations of students and researchers in mathematics. This volume summarizes and reviews the consistent themes from his work through a series of articles written by renowned experts. These articles contain original research work, set in a broader context by the inclusion of review material. As a reference text in its own right, this book will be valuable to academic researchers, research students, and others seeking an introduction to the relevant contemporary aspects of these fields.

Dominic Welsh has been the resident mathematician at Merton College, Oxford, for about 40 years, where he has guided and influenced generations of undergraduate and graduate students. Prior to his formal retirement in 2005, he was a Professor in the Mathematical Institute at Oxford University, where he served as Chairman for five years. Dominic Welsh is a leading figure worldwide in aspects of combinatorics and probability, including matroids, complexity, and percolation. Geoffrey Grimmett graduated under Dominic Welsh in 1971. He worked in Bristol University for 16 years before moving to Cambridge in 1992 as Professor of Mathematical Statistics. He is currently Head of the Department of Pure Mathematics and Mathematical Statistics, and a professorial fellow of Churchill College. His main interests lie in probability theory and rigorous statistical mechanics, and he is the author of successful texts on percolation theory and the random-cluster model. Colin McDiarmid gained his DPhil under Dominic Welsh in 1975. After a brief spell at the London School of Economics he became a fellow of Wolfson College, Oxford and then a fellow of Corpus Christi College. He is currently Professor of Combinatorics and Head of the Department of Statistics. His main interests lie in combinatorial theory, particularly in random structures and algorithms.
