Cp. Dettmann et Ne. Frankel, POTENTIAL-THEORY AND ANALYTIC PROPERTIES OF SELF-SIMILAR FRACTAL AND MULTIFRACTAL DISTRIBUTIONS, Journal of statistical physics, 72(1-2), 1993, pp. 241-275
By the use of recursion relations and analytic techniques we deduce ge
neral analytic results pertaining to the electrostatic potential, mome
nts, and Fourier transform of exactly self-similar fractal and multifr
actal charge distributions. Three specific examples are given: the bin
omial distribution on the middle-third Cantor set, which is a multifra
ctal distribution, the uniform distribution on the Menger sponge, whic
h illustrates the added complication of higher dimensionality, and the
uniform distribution on the von Koch snowflake, which illustrates the
effect of rotations in the defining transformations.
