Asymptotic and factorial expansions of Euler series truncation errors via exponential polynomials
Riccardo Borghi
A detailed analysis of the remainder obtained by truncating the Euler series up to the th-order term is presented. In particular, by using an approach recently proposed by Wenig…

Joint use of the Weniger transformation and hyperasymptotics for accurate asymptotic evaluations of a class of saddle-point integrals. II. Higher-order transformations
Riccardo Borghi
The use of hyperasymptotics and the Weniger transformation has been proposed, in a joint fashion, for decoding the divergent asymptotic series generated by the steepest descent on…
