Reason: Following publication of this paper, it was brought to our attention that a virtually identical paper had been published earlier:
B. Fisher and K. Tas. On the composition of the distributions x−r+ and xμ+, Indian Journal of Pure and Applied Mathematics 36 (2005) 11–22.
Furthermore, the following similar paper has also appeared:
B. Fisher and K. Tas. On the composition of the distributions x−1 ln x and xr+. Integral Transforms and Special Functions 16 (2005) 533–543.
When the JMAA paper was being submitted, the JMAA Editors were unaware that an almost identical version was under consideration elsewhere, and indeed, in the submission procedures, authors are asked to declare explicitly that this is not the case. Had this notification been given accordingly, the paper would not have been accepted.
The Editors deplore the practice of simultaneous multiple submission of papers to different journals, and offer their sincere and unreserved apologies to readers of the journal for not having spotted this.
