The Similarity Invariants of non-lightlike Frenet curves in the Minkowski 3-space

In this paper, we firstly introduce the group of similarity transformations in the Minkowski-3 space. We describe differential- geometric invariants of a non-lightlike curve according to the group of similarity transformations of the Minkowski 3-space. We show extension of fundamental theorem for non-lightlike curves under the group of similarity of the Minkowski 3-space.
