Geodesic connectedness and conjugate points in GRW space–times
نویسندگان
چکیده
Given two points of a Generalized Robertson-Walker spacetime, the existence, multiplicity and causal character of geodesics connecting them is characterized. Conjugate points of such geodesics are related to conjugate points of geodesics on the fiber, and Morse-type relations are obtained. Applications to bidimensional spacetimes and to GRW spacetimes satisfying the timelike convergence condition are also found. ∗Research partially supported by a MEC grant number PB97-0784-C03-01.

متن کاملA topological method for geodesic connectedness of space–times: Outer Kerr space–time
For a space–time, the question whether two causally related points can be joined by means of a causal geodesic has a clear physical meaning. More geometrically, geodesic connectedness ~the possibility of joining any two points by a geodesic of any causal type! is a basic property. Some techniques introduced to study geodesic connectedness are appliable to related problems of physical interest, ...
متن کامل1 6 Ju n 20 04 On the Geometry of Static Space – Times
We review geometrical properties of a static spacetime (M, g), including geodesic completeness, causality, standard splittings, compact M , closed geodesics and geodesic connectedness. We pay special attention to the critical quadratic behavior at infinity of the coefficients β, β −1 (β = −g(K, K), being K a timelike irrotational Killing vector field), which essentially control completeness, ca...

متن کاملGeodesic metric spaces and generalized nonexpansive multivalued mappings
In this paper, we present some common fixed point theorems for two generalized nonexpansive multivalued mappings in CAT(0) spaces as well as in UCED Banach spaces. Moreover, we prove the existence of fixed points for generalized nonexpansive multivalued mappings in complete geodesic metric spaces with convex metric for which the asymptotic center of a bounded sequence in a bounded closed convex...
