The Capacity of the Rational Preimage of a Compact Set

V. I. Buslaev

Steklov Mathematical Institute of Russian Academy of Sciences, Moscow

Abstract: It is shown that a well-known expression for the capacity of the preimage of a compact set under a polynomial map remains valid in the case of a rational map, provided that the standard capacity of the preimage is replaced by its capacity in the external field determined by the poles in $\mathbb C$ of the rational function determining the map.

Keywords: capacity, transfinite diameter, rational map, symmetric compact set.
