Abstract
]]> In these notes some examples of how to apply finite differencing to the solution of partial differential equations are presented and analyzed. The aim of this manuscript is to offer the reader a first step toward the numerical solution of sufficiently complicated and interesting problems within general relativity. The topics include the solution of the wave equation in one spatial dimension and the solution of real and complex self–gravitating scalar fields with spherical symmetry.Keywords: Numerical methods; numerical relativity; self–gravitating systems.
Resumen
En estas notas se presentan y analizan algunos ejemplos de aplicación del método de diferencias finitas a la solución de ecuaciones diferenciales parciales. La motivación de este manuscrito es ofrecer al lector un primer paso en la solución numérica de problemas suficientemente complicados e interesantes en relatividad general, o sea, dentro del area llamada relatividad numérica. Los temas incluyen la solución de la ecuación de onda en una dimensión espacial y la solución de campos escalares auto–gravitantes, tanto reales como complejos con simetría esférica.
Descriptores: Métodos numéricos; relatividad numérica; sistemas auto–gravitantes.
