This text describes the statistcal behavior of complex systems and shows
how the fractional calculus can be used to model the behavior. The
discussion emphasizes physical phenomena whose evolution is best
described using the fractional calculus, such as systems with long-range
spatial interactions or long-time memory. The book gives general
strategies for understanding wave propagation through random media, the
nonlinear response of complex materials, and the fluctuations of heat
transport in heterogeneous materials.
