Fractional calculus represents a natural instrument to model nonlocal or long-range dependence phenomena either in space or time. The processes that involve different space and time scales appear in a wide range of contexts from physics and chemistry to biology and engineering. In many of these problems the dynamics of the system can be formulated in terms of fractional differential equations which include the nonlocal effects either in space or time. We give a brief nonexhaustive panoramic view of the mathematical tools associated with fractional calculus as well as a description of some fields where either it is applied or could be potentially applied. 1. Introduction Fractional calculus see 1 offers a very suggestive and stimulating scenario where we have the convergence of deep and fundamental mathematical questions development of appropriate numerical algorithms as well as the applications to modelizations in different frameworks. An illustration of the physical applications of fractional calculus is the recent following books and special issues on applications on nanotechnology and other important topics 2-6 among many others. From a mathematical point of view the modelization of the long-range dependence is associated with integrodifferential
