WebDeformation space of circle patterns - Waiyeung LAM 林偉揚, BIMSA (2024-03-29) William Thurston proposed regarding the map induced from two circle packings with the same tangency pattern as a discrete holomorphic function. A discrete analogue of the Riemann mapping is deduced from Koebe-Andreev-Thurston theorem. Weblearn about circle theorems, 1. opposite angles in a cyclic quadrilateral are supplementary. 2. the exterior angle formed is equal to the interior opposite angle. 3. A radius is perpendicular to the tangent at the point of contact or tangency. 4. two tangents drawn from the same external point to a circle are equal.
