On renormalization of Poisson-Lie T-plural sigma models    [PDF]

Ladislav Hlavaty, Josef Navratil, Libor Snobl

Conditions for covariance of the one-loop renormalization group equations with respect to the Poisson Lie T-plurality of sigma models are formulated and investigated. Examples of nonequivalence of these equations under the Poisson Lie T-plurality are given. Role of ambiguities in renormalization group equations of Poisson-Lie sigma models with truncated matrices of parameters is discussed.
