Abstract
We use the Sáez–Ballester theory on anisotropic Bianchi I cosmological model, with barotropic flui and cosmological constant. We obtain the classical solution by using the Hamilton–Jacobi approach. Also the quantum regime is constructed and exact solutions to the Wheeler–DeWitt equation are found.
Keywords: Classical and quantum exact solutions; cosmology.
Resumen
Usamos la teoría de Sáez–Ballester en el modelo anisotrópico Bianchi I con un fluid barotrópico y constante cosmológica. Obtenemos las soluciones clásicas usando el enfoque de Hamilton–Jacobi. El regimen cuántico también es construido y soluciones exactas a la ecuación de Wheeler–DeWitt son encontradas.
Descriptores: Soluciones clásicas y cuánticas exactas; cosmología.
