On the comparison of two numerical methods for conformal mapping
Let G be a simply-connected domain in the t—plane (t = x + iy), bounded by the three straight lines x = 0, y = 0, x =1 and a Jordan arc with cartesian equation y = τ (X). Also, let g be the function which maps conformally a rectangle R onto G, so that the four corners of R are mapped onto those of G. In this paper we show that the method con-sidered recently by Challis and Burley [2], for determining approx- imations to g, is equivalent to a special case of the well-known method of Garrick [8] for the mapping of doubly-connected domains, Hence, by using results already available in the literature, we provide some theoretical justification for the method of [2]
Matrix methods and the property of stretchings
D. F. Dawson has proved that if

A

Growth of power series with square root gaps
For entire functions whose power series have Hadamard gaps with ratio , Gaier has shown that the condition for implies for all . Here the result is extended to the case of square root gaps, that is, with where . Smaller gaps cannot work. In connection with his proof of the general high indices theorem for Borel summability, Gaier had shown that square root gaps imply . Having such an estimate, one can adaptPitt's Tauberian method for the restricted Borel high indices theorem to show that, in fact, which implies . The author also states an equivalent distance formula involving monomials in
The Faber Operator and its Boundedness
AbstractLet G be a domain bounded by a Jordan curve Γ, and let A(G) be the Banach space of functions continuous on G and holomorphic in G. The Faber operator T is a linear mapping from A(D) to A(G) mapping wn onto the nth Faber polynomial Fn(z) (n=0, 1, 2, …). We show that ‖T‖<∞ if Γ is piecewise Dini-smooth, and give an example of a quasicircle Γ for which ‖T‖=∞
