• Dec 20, 2025 geometries and groups loped by Felix Klein in the 19th century, this program proposed classifying geometries by their symmetry groups. Core ideas: Geometries are characterized by their transformation groups. Properties invariant under these groups define the geometry. Group Theory and Geometry in the 20th Century Ad By Thelma Auer
