| Abstract: |
| In this paper, we study some properties about rectilinear congruences, especially about time-like congruences in a Minkowski 3-space. We firstly discuss the existence of the fundamental elements of congruences and then prove a result about the distribution parameters of time-like congruences in Minkowski 3-space which is a generalization of a result proved by Su Buchin in 1927. |
