Faber polynomials

From Wikipedia, the free encyclopedia

In mathematics, the Faber polynomials Pm of a Laurent series

\displaystyle f(z)=z^{{-1}}+a_{0}+a_{1}z+\cdots

are the polynomials such that

\displaystyle P_{m}(f)-z^{{-m}}

vanishes at z=0. They were introduced by Faber (1903, 1919) and studied by Grunsky (1939) and Schur (1945).
