Methods of Retrieving Large-Variable Exponents / V.I.Yukalov, S.Gluzman // Symmetry [Electronic resource]. – 2022. – Vol.14, No.2. – p.332. – URL: https://doi.org/10.3390/sym14020332. – Bibliogr.:35.

Methods of determining, from small-variable asymptotic expansions, the characteristic exponents for variables tending to infinity are analyzed. The following methods are considered: diff-log Padé summation, self-similar factor approximation, self-similar diff-log summation, self-similar Borel summation, and self-similar Borel–Leroy summation. Several typical problems are treated. The comparison of the results shows that all these methods provide close estimates for the large-variable exponents. The reliable estimates are obtained when different methods of summation are compatible with each other.
