Abstract

We investigate the cosmology of a class of model with noncanonical scalar field and matter in an anisotropic time dependent background. Writing the Einstein Equations in terms of dimensionless dynamical variables appropriately defined for bouncing solutions, we find all the fixed points. While evolving the dynamical variables to their stable fixed points numerically, solutions satisfying non singular bounce are found.
