摘要翻译:
应用自相似因子近似方法计算了O(N)-对称phi^4理论和Ising玻璃的临界指数。结果表明,该方法在计算临界指数方面比其它已知的级数求和方法简单得多,同时也得到了与其它较为复杂的数值方法一致的结果。自相似因子近似法的主要优点是它非常简单和高精度的结合。

英文摘要:
The method of self-similar factor approximants is applied to calculating the critical exponents of the O(N)-symmetric phi^4 theory and of the Ising glass. It is demonstrated that this method, being much simpler than other known techniques of series summation in calculating the critical exponents, at the same time, yields the results that are in very good agreement with those of other rather complicated numerical methods. The principal advantage of the method of self-similar factor approximants is the combination of its extraordinary simplicity and high accuracy.
