For a compact set E ⊂ C with connected complement, we study asymptotic behavior of normalized zero counting measures { μk } of the derivatives of Faber polynomials associated with E. For example if E has empty interior, we prove that { μk } converges in the weak-star topology to a probability measure whose support is the boundary of g (D), where g : { | z | > r } ∪ { ∞ } → over(C, -) {minus 45 degree rule} E is a universal covering map such that g (∞) = ∞ and D is the Dirichlet domain associated with g and centered at ∞. Our results are counterparts of those of Kuijlaars and Saff [Asymptotic distribution of the zeros of Faber polynomials, Math. Proc. Cambridge Philos. Soc. 118 (1995) 437-447] on zeros of Faber polynomials. © 2006 Elsevier Inc. All rights reserved.
