The Dual Expression of Parallel Equidistant Ruled Surfaces in Euclidean 3-Space

In this study, we examine the dual expression of Valeontis’ concept parallel p-equidistant ruled surfaces well known in Euclidean 3-space, according to Study mapping. Furthermore, show that part angle on unit sphere corresponds p-distance. We call these obtained “dual equidistant surfaces” and briefly denote them with “DPERS”. find Blaschke vectors, invariants striction curves DPERS give relationships between elements. Moreover, Darboux screws, instantaneous screw axes, Pfaff vectors Steiner rotation surfaces. Finally, an example, which reinforce article, explain all features figures example. see corresponding are such one is symmetric respect imaginary symmetry axis other.
