Abstract
In the framework of 4D EinsteinMaxwell DilatonAxion theory we show how to obtain a family of both unpolarized and polarized S1 x S2 Gowdy cosmological models endowed with nontrivial axion, dilaton and electromagnetic fields from a solitonic rotating black holetype solution by interchanging the r and t coordinates in the region located between the horizons of the black hole configuration. We also obtain a family of KantowskiSachs cosmologies with topology R1 x S2 from the polarized Gowdy cosmological models by decompactifying one of the compact dimensions.
Keywords: Gowdy and KantowskiSachs cosmological models; rotating black holes; lowenergy string theory; coordinate transformation.
Resumen
En el marco de la teoría tetradimensional de EinsteinMaxwell con dilaton y axión se muestra cómo obtener una familia de modelos cosmológicos de Gowdy (polarizados y no polarizados) con topología S1 x S2. Dichos modelos cosmológicos se obtienen a partir de una solución solitónica de tipo agujero negro rotatorio mediante el intercambio de las coordendas r y t en la región comprendida entre los horizontes del agujero negro y contempla campos dilatonico, axiónico y electromagnético no triviales. A su vez, a partir de las cosmologías de Gowdy polarizadas se obtiene una subclase de modelos cosmológicos de tipo KantowskiSachs con topología R1 x S2 mediante la decompactificación de una de las coordenadas compactas.
Descriptores: Cosmologías de tipo Gowdy y KantowskiSachs; agujeros negros rotatorios; teoría de cuerdas a bajas energías; transformación de coordenadas.
