D-Tangent surfaces of timelike biharmonic d-helices according to darboux frame on non-degenerate Timelike Surfaces in the Lorentzian Heisenberg GroupH

Abstract

In this paper, we study D-tangent surfaces of timelike biharmonic D-helices according to Darboux frame on non-degenerate timelike surfaces in the Lorentzian Heisenberg group H. We obtain parametric equation D-tangent surfaces of timelike biharmonic D-helices in the Lorentzian Heisenberg group H. Moreover, we illustrate the figure of our main theorem. © Soc. Paran. de Mat.
