Resolución numérica del problema de Bratu: diferencias finitas y métodos de continuación

Abstract

[ES] En este trabajo se lleva a cabo la resolución numérica del problema de Bratu unidimensional. Para ello se procederá, en primer lugar, a la discretización mediante diferencias finitas centradas de orden dos del mismo. A continuación, se construye la parametrización de las curvas de soluciones del problema continuo en entornos de puntos regulares y de puntos singulares simples; tras lo cual se inicia un estudio sobre la aproximación numérica de las soluciones del problema continuo por las del problema discreto correspondiente. También se presentan algunos tipos de funciones escalares que serán de utilidad a la hora de detectar los llamados puntos de retorno no degenerados, que son los que presenta la curva de soluciones del problema de Bratu. Finalmente, se implementa un método de continuación respecto al parámetro longitud de arco y se muestran los resultados numéricos obtenidos.
