The results are presented in terms of hypergeometric functions and confluent hypergeometric functions.
Provides introductory material to required mathematical topics such as complex numbers, Laplace and Fourier transforms, matrix algebra, confluent hypergeometric functions, digamma functions, and Bessel functions.
This gives an expansion analogous to the Poincare-type expansion, but including confluent hypergeometric functions instead of inverse powers of z as asymptotic sequence.
The purpose of this paper is to analyze some features of this modification, namely the convergence properties of the modified asymptotic series and some techniques that can be used to compute the confluent hypergeometric functions involved in the approximation.
These integrals can be written as confluent hypergeometric functions, by virtue of the integral representation[1, Eq.
8), the modified asymptotic series involves confluent hypergeometric functions as the asymptotic sequence.
0] = 1, so it is important to observe that in this setting there is no need for the actual computation of the confluent hypergeometric functions.
These techniques can be applied to several other examples within the family of confluent hypergeometric functions.
