"On Dimension of Equilibrium
Measures
on Small Sets"
By
Abstract: There are two natural measures on the classical Cantor set : the Cantor-Lebesgue measure (that is the Hausdorff measure with dimension log 2 / log 3), and the equilibrium measure that minimizes the logarithmic energy. Makarov and Volberg proved in 1986 that these measures are mutually singular. Some generalizations were obtained later for multidimensional fractals and for Cantor repellers. We discuss the possibility to construct Cantor-type sets for which these measures coincide or, at least, are not mutually singular.
