3 Asymptotic expansion of integrals. Introduction. There are special functions in physical applied mathematics (eg Gamma function,. Airy Function, Bessel. In this chapter, we give some examples of asymptotic expansions of integrals. following proposition shows that the series is an asymptotic expansion of I(x) as. asymptotic expansions of integrals, especially focusing on the asymptotic theory of complex Laplace-type integrals: the Method of Steepest.

A divergent asymptotic expansion. A convergent expansion can be easily obtained by integrating term by term the power series represen- tation of the integrand, while a divergent expansion is usually constructed using integration by parts. Depending on the limiting value, one is more favourable than the other. Part B: Asymptotic Expansions and Integrals.

W.R. Young 1. March 1Scripps Institution of Oceanography, University of California at San Diego, La Jolla. Asymptotic analysis, that branch of mathematics devoted to the study of the behavior of functions within chosen limits, was once thought of more as a specialized.

This paper gives an introduction to some of the most well-known meth- ods used for finding the asymptotic expansion of integrals.

The classical term-by-term integration technique used for obtaining asymptotic expansions of integrals requires the integrand to have an uniform asymptotic. 3 Asymptotic expansion of integrals. Introduction. There are special functions in physical applied mathematics (eg Gamma function,. Airy Function, Bessel.
