摘要: The first attempts at solving a binary black hole spacetime date back to the 1960s, with pioneering works of Hahn and Lindquist. In spite all computational advances enormous efforts by several groups, stable, long-term evolution orbit merger two holes was only accomplished over 40 years later, in 2005. Since then, field Numerical Relativity has matured, been extensively used explore uncover plethora physical phenomena various scenarios. this thesis, we take new frontiers exploring its extensions higher dimensions, non-asymptotically flat spacetimes Einstein-Maxwell theory. We start reviewing usual formalism tools, including "3+1" decomposition, initial data construction, BSSN scheme standard wave extraction procedures. then present dimensional reduction procedure that allows one use existing numerical codes (with minor adaptations) evolve higher-dimensional systems enough symmetry, show corresponding results obtained for five-dimensional head-on collisions holes. Finally, evolutions spacetimes,
