Ruled Surfaces with Timelike Rulings

Abstract

In this paper, using [E. Kasap, İ. Aydemir, N. Kuruoǧlu, Erratum to: "Ruled surfaces with timelike rulings" [Appl. Math. Comput. 147 (2004) 241-253], Applied Mathematics and Computation 168 (2005) 1461-1468 [2]], some mistakes which are related to the classification maximal ruled surfaces with timelike rulings in the last section of [Applied Mathematics and Computation 147 (2004) 241-253 [1]] have been found and corrected then re-written. © 2005.
