PARALLEL SURFACES TO S-TANGENT SURFACES OF BIHARMONIC S-CURVES ACCORDING TO SABBAN FRAME IN HEISENBERG GROUP HEIS 3

In this paper, we study parallel surfaces to S - tangent surfaces according to Sabban frame in the Heisenberg group Heis3. We characterize parallel surfaces to S - tangent surfaces of the biharmonic curves in terms of their geodesic curvature in the Heisenberg group Heis3. Finally, we find explicit parametric equations of parallel surfaces S - tangent surfaces according to Sabban Frame.
