A solution to the more than 300-years old problem of geometric and
physical interpretation of fractional integration and differentiation
(i.e., integration and differentiation of an arbitrary real order) is
suggested for the Riemann-Liouville fractional integration and differentiation,
the Caputo fractional differentiation, the Riesz potential, and the
Feller potential. It is also generalized for giving a new geometric
and physical interpretation of more general convolution integrals of
the Volterra type. |
