Topology of closed asymptotic curves on negatively curved surfaces
Mohammad Ghomi, Matteo Raffaelli
Motivated by Nirenberg's problem on isometric rigidity of tight surfaces, we study closed asymptotic curves on negatively curved surfaces in Euclidean -space. In particu…

-Principles for curves and knots of constant torsion
Mohammad Ghomi, Matteo Raffaelli
We prove that curves of constant torsion satisfy the -dense h-principle in the space of immersed curves in Euclidean space. In particular, there exists a knot of constant tors…
