Colapso gravitacional de fluido perfeito em espaços-tempos circularmente simétricos com auto-similaridade cinemática
Perfect fluid with kinematic self-similarity is studied in 2 + 1 dimensional spacetimes with circular symmetry and various exact solutions to the Einstein field equations are given. These include all the solutions of dust and stiff perfect fluid with self-similarity of the first kind (homothetic) …
