Timelike minimal helicoidal surfaces in Lorentz-Minkowski 3-space revisited
The author writes on time-like helicoidal minimal surfaces in Lorentz-Minkowski geometry. He starts with a review of Lorentz-Minkowski spaces then proves certain properties of isotropic helices with parallel axis. Then the author classifies time-like minimal helicoidal surfaces. Specifically, he shows that isotropic curves on these surfaces are isotropic helices.
