Non-null slant ruled surfaces

In this study, we define some new types of non-null ruled surfaces called slant ruled surfaces in the Minkowski 3-space $E_{1}^{3} $. We introduce some characterizations for a non-null ruled surface to be a slant ruled surface in $E_{1}^{3} $. Moreover, we obtain some corollaries which give the relationships between a non-null slant ruled surface and its striction line.
