books.google.ru - This text describes how fractal phenomena, both deterministic and random, change over time, using the fractional calculus. The intent is to identify those characteristics of complex physical phenomena that require fractional derivatives or fractional integrals to describe how the process changes over...http://books.google.ru/books/about/Physics_of_Fractal_Operators.html?hl=ru&id=EgyTpQZOga0C&utm_source=gb-gplus-sharePhysics of Fractal Operators
