A note on the squeezing function

Complex Variables 2021-01-12 v1

Abstract

The squeezing problem on C\mathbb{C} can be stated as follows. Suppose that Ω\Omega is a multiply connected domain in the unit disk D\mathbb{D} containing the origin z=0z=0. How far can the boundary of Ω\Omega be pushed from the origin by an injective holomorphic function f:ΩDf:\Omega\to \mathbb{D} keeping the origin fixed? In this note, we discuss recent results on this problem obtained by Ng, Tang and Tsai (Math. Anal. 2020) and by Gumenyuk and Roth (arXiv:2011.13734, 2020) and also prove few new results using a method suggested in one of our previous papers (Zapiski Nauchn. Sem. POMI 1993).
