“…There are many applications of Bishop frames in differential geometry such as [1, 3,8,9,10,11,12,17,19,20]. Up to now, different types of surfaces and curves such as ruled surfaces [9,20], tubular surfaces [8], special Bishop motion and Bishop Darboux rotation axis of the space curve [3] and B-canal surfaces in terms of biharmonic B-slant helices in Heisenberg group Heis 3 [10] have been studied according to Bishop frames. Inspired by the work of Bishop, in [9], the authors introduced the ruled surface with Bishop frame N 2 (s) as its directrix, i.e., ϕ(s, t) = γ(s) + uN 2 (s), which they also called N 2 (s)-ruled surface with the Bishop frame.…”
