Asymptotic Expansions of Integrals. Norman Bleistein , Richard A. 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 art than a necessary discipline. Now, a solid foundation in the theory and technique of asymptotic expansion of integrals is at the heart of the education of every student concentrating in applied mathematics. It is also an invaluable asset to scientists in many other fields.

The technique used to obtain the uniform expansion is an adaptation of the method originally developed by Chester , Friedman and Ursell in their treatment of the problem of two nearby stationary points.
Here, however, we find that a certain family of Bessel functions play the role of the Airy functions in that problem. In fact a theorem is proved which establishes the asymptotic nature of our results in the relevant limits. Finally, two examples are considered to illustrate the use of these results.
