Pseudo Focal Points Along Lorentzian Geodesics and Morse Index
(ADVANCED NONLINEAR STUDIES, INC, 2010)
Given a Lorentzian manifold (M,g), a geodesic gamma in M and a timelike Jacobi field Y along gamma, we introduce a special class of instants along gamma that we call Y-pseudo conjugate (or focal relatively to some initial ...
Symmetry breaking and Morse index of solutions of nonlinear elliptic problems in the plane
(2016-10-01)
In this paper, we study the problem {equation presented} where B1 is the unit ball of R2, f is a smooth nonlinearity and α, λ are real numbers with α > 0. From a careful study of the linearized operator, we compute the ...

Morse index and bifurcation of p-geodesics on semi Riemannian manifolds
(EDP SCIENCES S A, 2007)
Given a one-parameter family {g(lambda) :lambda is an element of [ a, b]} of semi Riemannian metrics on an n-dimensional manifold M, a family of time-dependent potentials {V-lambda: lambda is an element of [a, b]} and a ...
