Fractal
structures are found everywhere in nature, and as a consequence
anomalous diffusion has far-reaching implications for a host of
phenomena. This book describes diffusion and transport in disordered
media such as fractals, porous rocks, and random resistor networks.
Part one contains material of general interest to statistical
physics:fractals,percolation theory, regular random walks and
diffusion,continuous-time random walks and Levy walks and flights.
Part two covers anomalous diffusion in fractals and disordered
media,while
Part three serves as an introduction to the kinetics of
diffusion-limited reactions.
Part four discusses the problem of diffusion-limited coalescence
in one dimension.
This book, written in a pedagogical style,is intended for upper-level
undergraduates and graduate students studying physics, chemistry,
and engineering. It also will be of particular interest to young
researchers requiring a clear introduction to the field.
