Stokes Phenomenon and Matched Asymptotic Expansions

open access: yesSIAM Journal on Applied Mathematics, 1995
This paper describes the use of matched asymptotic expansions to illuminate the description of functions exhibiting Stokes phenomenon. In particular the approach highlights the way in which the local structure and the possibility of finding Stokes ...

Asymptotic Expansions

Canadian Journal of Mathematics, 1956
1. Introduction. Let a1 a2, …, am be a set of real non-negative numbers and let1.1 P(x) = a1x + a2x2 + … + amxm (am ≠ 0).Many combinatorial problems can be reduced to the study of numbers Bn generated by1.2.Some problems of this type were treated by Touchard (7), Jacobsthal (3), Chowla, Herstein, Moore and Scott (1; 2), and the present authors (4).

Asymptotic Expansions II

Canadian Journal of Mathematics, 1957
In a previous paper (1) the authors considered the problem of finding an asymptotic formula for numbers or functions Bn,m whose generating function is of the form(1.1),where Pm(x) is a polynomial of degree m in x given by(1.2), am≠0.The above-mentioned paper contained the ...

Generic Asymptotic Expansions

Applicable Algebra in Engineering, Communication and Computing, 1998
The author gives an expansion algorithm for germs of exp-log functions at infinity, which is correct modulo Schanuel's conjecture. He also shows how the algorithm can be made generic.

Perturbation Expansion: Is it Asymptotic?

Modern Physics Letters A, 1997
It is pointed out that, for any model with bound state, contrary to the case of nonrelativistic quantum mechanics, perturbation expansion based on Feynman rules in relativistic quantum field theory is not asymptotic of physical amplitude in which the effects of bound state are considered.
