It would take a careful inventory to assess accurately. Both Tristan Needham's Visual Complex Analysis and Marcel Berger's A Panoramic View of Riemannian Geometry consistently use lowercase for point labels in diagrams. A.D. Alexandrov's Convex Polyhedra solely uses uppercase (ca. 1950). I love your French origins theory! :-) | |
