Abstract

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 these methods to the \(O(n)\)-symmetric \({{\phi }^{4}}\) model with a real antisymmetric tensor order parameter will be presented.

异常维数六环结果求和矩阵阶参数模型的临界指数

摘要

在这篇文章中,将讨论两种用于渐近级数求和的技术的应用,即 Borel-Pade 技术和带有保形映射的 Borel-Leroy 技术在具有多个耦合常数的模型的情况下,并将这些方法应用于\ (O(n)\) - 对称\({{\phi }^{4}}\)模型与一个真正的反对称张量阶参数将被提出。
