The optimal Lipschitz maps between Euclidean triangles
摘要
We find a homeomorphism (or a sequence of homeomorphisms) with the smallest Lipschitz constant between two given Euclidean triangles (that is, acute triangles, right triangles, and obtuse triangles) with fixed area and we give a formula for the Lipschitz constant of this map. As applications of our results, we consider some special cases of the smallest Lipschitz constant between two quadrangles.
