摘要：

Recent work on extrapolative processes for a class of infinite oscillatory integrals is extended by a procedure which involves the unknown abscissae at which the remainder integral vanishes identically. The asymptotic proximity of these abscissae to a known set is used as a basis for further extrapolation. Results show that the method can be useful for the very slowly converging integrals whose amplitudes decay only algebraically. © 1990 BIT Foundations.
