BOUR'S THEOREM UNDER THE CONFORMAL MAP WITH LIGHT LIKE PROFILE CURVE
Abstract
A generalized helicoid and a rotational surface have an isometric relation
by Bour's theorem. It is that "A generalized helicoid is isometric to a
rotational surface. Hence, helices on the helicoid can be transformed to
parallel circles on the rotational surface under the isometric
transformation".
In this study, we give a conformal relation between a generalized helicoid
(with lightlike profile curve) and a spiral surface (with lightlike profile
curve). In this sitiutation, we can say that helices on the helicoid can be
transformed to spirals on the spiral surface under the conformal
transformation. Also, some related examples and their figures are given.
