Surfaces with isothermal representation of their lines of curvature and their transformations
Surfaces with isothermal representation of their lines of curvature and their transformations
IN a former lnemoir with the same title t we established a transformation of surfaces with isothermal spherical representation of their lines of curvature into surfaces of the same kind, the transformation being such that lines of curvature on a surface and on a transform correspond, and the two surfaces …
