The $1/N$-expansion for flag-manifold $\sigma$-models
D. V. Bykov Steklov Mathematical Institute of Russian Academy of Sciences, Moscow, Russia
Abstract:
We derive the Feynman rules for the $1/N$-expansion of the simplest $\sigma$-model in the class of models that we previously proposed. We consider the case where the target space is the flag manifold $\frac{U(N)}{U(1)\times U(1)\times U(N-2)}$.
Keywords:
$\sigma$-model, Feynman rule, $1/N$-expansion.
