Quasiconformal Reflection with Respect to the Boundary of an Isosceles Trapezoid
摘要
Abstract
We establish an upper estimate for the coefficient of quasiconformal reflection with respect to the boundary of an arbitrary isosceles trapezoid in terms of its geometric parameters; the estimate improve the result obtained in the recent paper by S. Nasyrov, T. Sugawa, and M. Vuorinen.
