On the possible fractal nature of blazar light curves

Optical light curves of three blazars are analyzed by Hurst’s method of normalized range. It is shown that Hurst’s empirical relationship is satisfied for these curves, in accordance with which the Hurst parameters are found for each curve. Assuming that blazar light curves have self-affinity, they determine the fractal dimensionality of the curves to be D ≈ 1.1. Translated from Astrofizika, Vol. 40, No. 3, pp. 341–348, August, 1997.
