Jul 8, 2023 · In this study, we first define the Smarandache curves derived from the Frenet vectors and the Darboux vector of any curve. The Darboux vector provides a concise way of interpreting curvature κ and torsion τ geometrically: curvature is the measure of the rotation of the Frenet frame about the binormal unit vector, whereas torsion is the measure of the rotation of the Frenet frame about the tangent unit vector. It is the analog of the Frenet – Serret frame as applied to surface geometry. It is also called angular momentum vector, because it is directly proportional to angular momentum. In About: Darboux vector In differential geometry, especially the theory of space curves, the Darboux vector is the angular velocity vector of the Frenet frame of a space curve. Abstract We study curves whose position vector always lies in the planes spanned by Darboux frame along the curves on the surface. among all adapted frames on a space curve, the RMF identifies least elastic energy associated with twisting (as distinct from bending) Frenet frame (center) & rotation-minimizing frame (right) on space curve In differential geometry, especially the theory of space curves, the Darboux vector is the angular velocity vector of the Frenet frame of a space curve. A Darboux frame exists at any non- umbilic point of a surface embedded in Euclidean space. In differential geometry, especially the theory of space curves, the Darboux vector is the angular velocity vector of the Frenet frame of a space curve. Frenet vector fields form an orthonormal frame along a space curve. [2] It is also called angular momentum vector, because it is directly proportional to angular momentum. The above basis in conjunction with an origin at the point of evaluation on the curve define a moving frame, the Frenet–Serret frame (or TNB frame). Explain how the normal and geodesic curvatures are recovered from the Darboux frame, as well as how one might compute these values from the curvature of our curve and the angle between the Darboux and Frenet frames. . It is named after Gaston Darboux who discovered it. Also, the relationships between Frenet and Darboux frames and Darboux vectors belong to these frames are given. It is named after French mathematician Jean Gaston Darboux. This is the Bishop frame. We can get an ODE to compute the Bishop frame. The first vector T of the Frenet - Serret frame (T, N, B) is tangent to a curve, and all three vectors are mutually orthonormal. The Darboux frame is composed of a tangent vector, normal vector, and the tangent normal vector. Jan 31, 2018 · What's the relation between the Darboux Frame and the Frenet-Serret on a oriented surface? Apr 30, 2025 · Referring to Figure 9, recall that the orthonormal and right-handed Frenet triad associated with the space curve satisfies the Serret-Frenet relations (9), yielding the Darboux vector in terms of the space curve’s geometric torsion and curvature . The Darboux frame is an example of an adapted frame that specifically applies to curves on surfaces in R3. [1] It is named after Gaston Darboux who discovered it. This frame field is called the Frenet frame which includes important knowledge about the curve. Jun 30, 2022 · The paper introduces a new kind of special ruled surface. Feb 20, 2020 · Details and Options The Darboux vector of a space curve with unit speed is the angular velocity vector of the Frenet frame. Apr 12, 2022 · Wang and Pei defined the Darboux vector of the null curve in [23] and described the direction of the rotation axis of the Cartan frame in Minkowski 3-space. It is named after French mathematician Jean Gaston The first vector T of the Frenet–Serret frame (T, N, B) is tangent to a curve, and all three vectors are mutually orthonormal. [1] It is named after Gaston Darboux who discovered it. This is the reason why both frames always have the velocity vector of the curve in it. May 11, 2019 · The Frenet frame is used to study curves, while the Darboux frame is used to study curves in surfaces. In general, frames should be adapted to whatever geometric object you're trying to study. Then, we construct new ruled surfaces along these Smarandache curves with The Darboux vector provides a concise way of interpreting curvature κ and torsion τ geometrically: curvature is the measure of the rotation of the Frenet frame about the binormal unit vector, whereas torsion is the measure of the rotation of the Frenet frame about the tangent unit vector. The base of each ruled surface is taken to be one of the Smarandache curves of a given curve according to Frenet frame, and the generator In this paper, we calculate the Frenet frame and Darboux vector of the dual curve (X) for the dual-spherical motion K/K on D-modul, corresponds to one-parameter motion H/H , where H and H denote the fixed and moving line-spaces, respectively. For curves on the surface, we define as the osculating Darboux curve when the position vector of always lies in the tangent plane of the surface and define as the rectifying Darboux curve when the position vector of always lies in the Darboux rectifying plane. Darboux frame In the differential geometry of surfaces, a Darboux frame is a natural moving frame constructed on a surface. Later, in 2017, Düldül [27] extended the Darboux frame field to four-dimensional Euclidean space and gave the relationship between the curvature of Frenet frame and Darboux frame. The derivatives of the vectors are parallel to the cross product of the original frame and the Darboux vector. In the differential geometry of surfaces, a Darboux frame is a natural moving frame constructed on a surface. N is the normal unit vector, the derivative of T with respect to the arclength parameter of the curve, divided by its length. We get two other orthogonal vectors twisting around the straw. Figure 9. Frenet formulas, which consist of the derivative equations of the Frenet frame, can be rewritten using the Darboux vector field in Euclidean 3-space 3, [1], [2]. Similarly, the Darboux frame on a surface is an orthonormal frame whose first two vectors are tangent to the surface.
