On k-type pseudo null Darboux helices in Minkowski 3-space

摘要

In this paper, we introduce k-type pseudo null Darboux helices in Minkowski 3-space, for k is an element of {1,2,3}. We obtain the relationship between 1-type and 2-type pseudo null Darboux helices and show that all 3-type pseudo null Darboux helices are also 1-type and 2-type helices, but the converse does not hold. Finally, we give some examples. (C) 2016 Elsevier Inc. All rights reserved.
