Interaction of goldstone particles in two dimensions. Applications to ferromagnets and massive Yang-Mills fields
Abstract
Interaction of Goldstone particles in two dimensions lead to the infrared catastrophe. In order to analyze it we apply to the problem the method of the renormalization group. It is shown that due to interaction the regime of the ``asymptotic freedom'' arises. The continuation to higher dimensions and the applications of the result are briefly discussed.
