Abstract:
A fractional differential equation is derived that describes the transformation of a stochastic transport from fast spreading ((x) over bar proportional to t (alpha), alpha > 1) to a pseudowave regime (alpha = 1) due to the finiteness of the velocities of individual particles. Qualitative features of the new regime are discussed. (C) 2002 MAIK "Nauka / Interperiodica".
