The area of reduced spherical polygons

Metric Geometry 2020-09-29 v1 Combinatorics

Abstract

We confirm two conjectures of Lassak on the area of reduced spherical polygons. The area of every reduced spherical non-regular nn-gon is less than that of the regular spherical nn-gon of the same thickness. Moreover, the area of every reduced spherical polygon is less than that of the regular spherical odd-gons of the same thickness and whose number of vertices tends to infinity.
