New Features about Chaos in Bianchi I non‐Abelian Born‐Infeld cosmology

When the action is replaced by the Born‐Infeld‐type non‐Abelian action (NBI), a chaos‐order transition is observed in the high energy region for a Bianchi I cosmology with the homogeneous SU(2) Yang‐Mills field. This is interpreted as a smothering effect due to (non‐perturbative in α′) string corrections to the classical EYM action. We give a numerical evidence for the chaos‐order transition and present an analytical proof of regularity of color oscillations in the limit of strong Born‐Infeld non‐linearity.
