Calibrated geodesic foliations of hyperbolic space
(American Mathematical Society, 2016-01)
Let H be the hyperbolic space of dimension n + 1. A geodesic foliation of H is given by a smooth unit vector field on L all of whose integral curves are geodesics. Each geodesic foliation of L determines an n-dimensional ...

A version of the Hermite--Hadamard inequality in a nonpositve curvature space
(Banach Mathematical Research Group, 2012-06)
We obtain some Hermite-Hadamard type inequalities for convex functions in a global non-positive curvature space.
The magnetic flow on the manifold of oriented geodesics of a three dimensional space form
(Osaka University. Departments of Mathematics, 2013-09)
Let M be the three dimensional complete simply connected manifold of constant sectional curvature 0,10,1 or −1−1. Let L be the manifold of all (unparametrized) complete oriented geodesics of M, endowed with its canonical ...
Genericity of Nondegenerate Critical Points and Morse Geodesic Functionals
(INDIANA UNIV MATH JOURNAL, 2009)
We consider a family of variational problems on a Hilbert manifold parameterized by an open subset of a Banach manifold, and we discuss the genericity of the nondegeneracy condition for the critical points. Using classical ...

COMPARISON RESULTS FOR CONJUGATE AND FOCAL POINTS IN SEMI-RIEMANNIAN GEOMETRY VIA MASLOV INDEX
(PACIFIC JOURNAL MATHEMATICS, 2009)
We prove an estimate on the difference of Maslov indices relative to the choice of two distinct reference Lagrangians of a continuous path in the Lagrangian Grassmannian of a symplectic space. We discuss some applications ...
Cosmological singularity theorems for f(R) gravity theories
(IOP Publishing, 2016-05)
In the present work some generalizations of the Hawking singularity theorems in the context of f(R) theories are presented. The main assumptions are: the matter fields stress energy tensor satisfies the condition ...
