Almost quarter-pinched Kähler metrics and Chern numbers
Martin Deraux, Harish Seshadri
We prove that compact Kähler manifolds whose sectional curvatures are close to 1/4-pinched have ratios of Chern numbers close to the corresponding ratios of a complex hyperbolic sp…
Two-Dimensional Almost-Riemannian Structures with Tangency Points
Andrei Agrachev, Ugo Boscain, Grégoire Charlot +2
Two-dimensional almost-Riemannian structures are generalized Riemannian structures on surfaces for which a local orthonormal frame is given by a Lie bracket generating pair of vect…
Lindelöf's theorem for catenoids revisited
Pierre Bérard, Ricardo Sa Earp
In this paper we study the maximal stable domains on minimal catenoids in Euclidean and hyperbolic spaces and in . We in particular investigate whether half-vertical…
Existence of planar curves minimizing length and curvature
Ugo Boscain, Grégoire Charlot, Francesco Rossi
In this paper we consider the problem of reconstructing a curve that is partially hidden or corrupted by minimizing the functional , depending both on lengt…
