Witryna4 sie 2024 · A flattened version of links in a thickened surface is immersed curves in a surface. Let L ( Σ) denote the set of all links in Σ × [ 0, 1], and let C ( Σ) denote the set of all (multi-)curves in Σ. There is a map L ( Σ) → C ( Σ) given by projection. Witrynaimmersed H4-initial curves. Moreover, they prove that the surface di usion ow can drive an initially embedded curve to a self intersection. The techniques in [14, 21] seem to be restricted to two dimensions. Our methods work in any dimension and we obtain existence and uniqueness for immersed hypersurfaces.
