Lines of curvature of the double torus
María García Monera, Vinicio Gómez Gutiérrez, Federico Sánchez-Bringas
We describe the -lines of curvature of an embedding of the double torus into , defined as the link of the real part of the Milnor fibration of a polynomial, where $…
On Lorentzian surfaces in
Pierre Bayard, Victor Patty, Federico Sánchez-Bringas
We study the second order invariants of a Lorentzian surface in and the curvature hyperbolas associated to its second fundamental form. Besides the four natural…
On the Arnold's conjecture on hyperbolic homogeneous polynomials
Adriana Ortiz-Rodríguez, Federico Sánchez-Bringas
The Hessian Topology is a subject with interesting relations with some classical problems of analysis and geometry. In this article we prove a conjecture on this subject stated by…
Geometric invariants and principal configurations on spacelike surfaces immersed in R^3,1
Pierre Bayard, Federico Sánchez-Bringas
We first describe the numerical invariants attached to the second fundamental form of a spacelike surface in four-dimensional Minkowski space. We then study the configuration of th…
