The extremal function for the complex ball for generalized notions of degree and multivariate polynomial approximation (vol 123, pg 171, 2019)

摘要

We correct our calculation from the paper in the title of the Monge-Ampere measure for the P-infinity-extremal function of the complex Euclidean ball in C-2. In addition, we indicate how the Monge-Ampere measures for the corresponding P-q-extremal functions vary with q.
