1. Análise de geometrias com curvas fechadas no tempo / Analysis of Geometries with Closed Timelike Curves.
This work deals with the analysis of cylindrically symmetric and stationary space-times Ct with closed timelike curves. The equation of motion describing the evolution of a massive scalar field in a Ct space-time is obtained. A class of space-times with closed timelike curves describing cosmic strings and cylinders is studied in detail. In such space-times,
