Loop quantum non-mixmaster universe

We explain the mixmaster behavior, studied by Misner for a Bianchi IX universe. We study how this behavior is modified by the loop quantum effects. We show that there is an isotropization process, some classical solutions are discarded and the potential walls of the classical theory are modify such that there is no chaotic behavior. Additionally, we show that the triangular symmetry of the classical theory (associated with the Misner variables) is still present, but the qualitative behavior in the anisotropic directions changes drastically due to the quantum effects.
