Siegel-Surgery according to Gaofei Zhang

    Research output: Contribution to conferencePosterResearch

    Abstract

    In a recent manuscript Gaofei Zhang has shown using quasi-conformal surgery, that the Siegel disk for the rotated sine function EXP(i2πθ)sin(z) is a quasi-disk passing whose boundary passes through the two neighbouring critical points ±π/2. His construction is similar in spirit to surgery constructions by first A. Doaudy and later by A. Cheritat. However the argument of Zhang is easily adaptable to many situations, including those studied by Douady and Cheritat.
