Homotopy type of spaces of locally convex curves in the sphere S^3
Emília Alves, Victor Goulart, Nicolau C. Saldanha
Locally convex (or nondegenerate) curves in the sphere have been studied for several reasons, including the study of linear ordinary differential equations of order . Ta…
Characterization of some convex curves on the 3-sphere
Emília Alves
In this paper we provide a characterization for a class of convex curves on the 3-sphere. More precisely, using a theorem that decomposes a locally convex curve on the 3-sphere as…
Results on the homotopy type of the spaces of locally convex curves on
Emília Alves, Nicolau C. Saldanha
A curve of class () is locally convex if the vectors are a positive orthonormal basis to $R…
Topology of the space of locally convex curves on the 3-sphere
Emília Alves
A (positive) locally convex curve in the 2-sphere is a curve with positive geodesic curvature (i.e., which always turns left). In the 3-sphere, it is a curve with positive torsion.…
