ON THE MINIMALITY AND TOTAL DEVELOPABILITY OF THE TIME-LIKE RULED SURFACES WITH THE TIME-LIKE GENERATING SPACE IN THE MINKOWSKI SPACE $IR^n_1$

Abstract

The purpose of this paper is, first, to introduce a summary of known results and the definition of the time-like ruled surface with the time-like generating space in the Minkowski space $IR^n_1$ (Section 1); second, to present some characteristic results related with minimality and total developability of the ruled surface in the Minkowski space $IR^n_1$ (Section 2).
