Critical exponents of model with matrix order parameter from resummation of six-loop results for anomalous dimensions

In this contribution an application of two techniques for resummation of asymptotic series namely Borel-Pade technique and Borel-Leroy technique with conformal mapping to the case of a model with multiple coupling constants will be discussed and the results of application of this methods to the $O(n)$-symmetric ${\varphi }^4$ model with an antisymmetric tensor order parameter will be presented.
