In the past few years there has been an explosion of activity in the field of dynamics of fractal surfaces, which, through the convergence of important new results from computer simulations, analytical theories and experiments, has led to significant advances in our understanding of nonequilibrium surface growth phenomena. This interest in surface growth phenomena has been motivated largely by the fact that a wide variety of natural and industrial processes lead to the formation of rough surfaces and interfaces. This book presents these developments in a single volume by bringing together the works containing the most important results in this field. The material is divided into chapters consisting of reprints related to a single major topic. Each chapter has a general introduction to a particular aspect of growing fractal surfaces. These introductory parts are included in order to provide scientific background for the papers reproduced in the main part of the chapters. They are written in a pedagogical style and contain only the most necessary information. The contents of the reprints are made more accessible to the reader by preceding them with a short description of what the editors find to be the most significant results in the paper.
