Bartolo, Rossella; Candela, Anna Maria Normal trajectories in stationary spacetimes under the action of an external field with quadrant asymptotic behavior. (English) Zbl 1171.53333 Extr. Math. 23, No. 3, 243-253 (2008). Summary: The aim of this note is to study the existence of normal trajectories joining two given submanifolds under the action of an external field in a standard stationary space-time. Here, it is assumed that both the growth of the potential and that of the coefficients of the metric are critical in a suitable sense.
