摘要:  The inner radius of univalency of a domain is greater than zero if and only if the domain is a quasidisc.However,little is known about the value of the inner radius of univalency for various quasidiscs.In this paper,we will use the comparison principal and obtain the value of the inner radius of univalency of the rhombus domain.

关键词: Schwarzian derivative, inner radius of univalency
