Abstract
We consider Axion-like particle (ALP) model to construct numerical spatially homogeneous anisotropic Kantowski-Sachs cosmological model. We present various analytical and numerical results in this regard, discussing the evolution of various important cosmological parameters in this regard with ALP scalar field. We also present some general results for generic scalar field in a Kantowski-Sachs background.
