| description | Introduction/purpose: Saddle point approximation has been considered
in the paper
Methods: The saddle point method is used in several different fields of
mathematics and physics. Several terms of the expansion for the factorial function have been explicitely computed.
Results: The integrals estimated in this way have values close to the
exact one.
Conclusions: Higher order corrections are not negligible even when requiring moderate levels of precision. |
