WebUnit disk. In mathematics, the open unit disk (or disc) around P (where P is a given point in the plane ), is the set of points whose distance from P is less than 1: The closed unit disk … WebWe obtain an explicit uniform upper bound for the derivative of a conformal mapping of the unit disk onto a convex domain. This estimate depends only on the outer and inner radii of the domain, and on the minimum curvature radius of its boundary. Its proof is based on a Möbius invariant metric of hyperbolic type, introduced by Kulkarni and Pinkall in 1994.
