ON THE LOCATION OF THE ZEROS OF FABER POLYNOMIALS
Analysis, 2000Let \(\Omega\) denote a compact set in \(\overline\mathbb{C}\), \(\Omega \neq\{a\}\) and such that \(\overline\mathbb{C}\setminus\Omega\) is a simply connected domain. Suppose that \(F_n(z)\) denotes the \(n\)-th Faber polynomial for \(\Omega\). It is known that if \(\Omega\) is a convex set, \(int(G)\neq \emptyset\), then all the zeros of \(F_n(z ...

The Faber polynomials for circular lunes
Let \(D_\alpha\) be the circular lune symmetric with respect to both axis with vertices at \(z = \pm \alpha\) and exterior angle \(\alpha \pi\), \(0 < \alpha \leq 2\). Let \(z = \psi (w) = w + \sum^\infty_{k = 0} b_k w^{-k}\) map \(\{w : |w |> 1\}\) conformally onto the exterior of \(D_\alpha\).

Faber Polynomials on Quaternionic Compact Sets
Complex Analysis and Operator Theory, 2017The authors consider the notion of Faber polynomials in the context of slice regular quaternionic functions. Let \(K\) be an axially symmetric compact set in \(\mathbb H\) (the skew field of real quaternions) such that \(\overline{\mathbb H}\setminus K\) is simply connected, then a given quaternionic function which is continuous on \(K\) and slice ...

Exact estimates for Faber polynomials and for norm of Faber operator
Complex Variables and Elliptic Equations, 2019Exact estimates for Faber polynomials, norm of Faber operator, and L1-norm of the generating function for the sequence of Faber operator of univalent functions of class Σ are found.

The conformal ‘bratwurst’ mapsand associated Faber polynomials
Numerische Mathematik, 2000In the construction of polynomial iteration methods for the solution of a linear system \(Ax= b\), it is necessary to find inclusion sets \(\Omega\) which contain the spectrum of \(A\) but \(0\not\in\Omega\). The main object of this paper is to construct explicitly a class of non-convex inclusion sets.

Lattice Paths and Faber Polynomials
1997The r-th Faber polynomial of the Laurent series f(t) = t + f 0 + f 1/t + f 2/t 2 + … is the unique polynomial F r (u) of degree r in u such that F r (f) = t r + negative powers of t. We apply Faber polynomials, which were originally used to study univalent functions, to lattice path enumeration.

Application of Faber Polynomials in Proving Combinatorial Identities
Ukrainian Mathematical Journal, 2018Suppose \(K\) is a compact subset of \(\mathbb C\) containing at least \(2\) points. If the complement of \(K\) in the Riemann sphere \(\overline{\mathbb C}=\mathbb C\cup\{\infty\}\) is simply connected, then the Riemann mapping theorem guarantees that there exists a unique biholomorphic map \(\Phi:\overline{\mathbb C}\setminus K\to\{w\in\overline ...

Supplement to Explicit Faber Polynomials on Circular Sectors
Mathematics of Computation, 1992This is an appendix to the paper reviewed above. There it is shown how the coefficients of the Faber polynomials on circular sectors \(S_ \alpha\) can be represented in terms of polynomials in \(c:=\alpha(2\pi- \alpha)/\pi\). For Faber polynomials up to degree 20 all the corresponding polynomials in \(c\) are given.
