We introduce Cartan ribbons, a novel method for approximating surfaces with intrinsically flat ribbons. This technique simplifies topological analysis by examining ribbon edge organization, applicable to surfaces like tori and ellipsoids.
Area of Science:
- Differential Geometry
- Computational Geometry
- Topology
Background:
- Approximating complex surfaces is crucial in various scientific fields.
- Existing methods may lack intrinsic flatness or topological simplicity.
Purpose of the Study:
- To develop a novel method for surface ribbonization using Cartan ribbons.
- To enable simplified topological analysis of surfaces through ribbon organization.
Main Methods:
- Introduced the concept of Cartan ribbons.
- Developed a rolling-based method for surface approximation.
- Ensured geodesic curvature alignment between surface and development curves using Darboux frames.
- Utilized closed contact centre curves for closed ribbon generation.
Main Results:
- Achieved intrinsically flat ribbon approximations of surfaces.
- Obtained closed Cartan ribbons with zero total curvature integral.
- Demonstrated simplified topological inspection based on ribbon edge arrangement.
- Successfully ribbonized a torus and an ellipsoid.
Conclusions:
- Cartan ribbons offer an effective method for surface approximation and topological analysis.
- The rolling-based approach ensures intrinsic flatness and simplifies complex surface studies.
- The method provides a new perspective on surface topology through ribbon organization.
