Bessel transforms and rational extrapolation. (English) Zbl 0554.65010
A numerical method is developed which handles the Bessel transform of functions having slow rates of decrease, i.e. \(f(u)=O(u^{-\alpha})\), \(u\to +\infty\) \((\alpha >0)\) in the Bessel transform \(H_ v(\lambda)=\int^{\infty}_{0}f(u)J_ v(\lambda u)du,v>-1/2.\) The method replaces \(H_ v\) by a related damped transform for which the sinc quadrature rule provides an efficient and accurate approximation. It is then shown that the value of \(H_ v(\lambda)\) can be obtained from the damped transform by extrapolation with the Thiele algorithm.
