The analogue of a Taylor series for fractal functions was derived by treatm
ent of anomalous dielectric relaxation in inhomogeneous media with chaotic
structure within the frame of the fractional integro-differential calculus
technique. Analysis of a classical problem of polarization of an inhomogene
ous medium permitted us to establish the relationship between anomalous rel
axation and dimensionality of a temporal fractal ensemble which characteriz
es a non-equilibrium state of a medium.
