Topic #6 ---------------- OP-SF NET ---------------- June 16, 1994
From: Tom H. Koornwinder <thk@fwi.uva.nl>
Subject: Formula list on Askey-Wilson polynomials and their limits
The following report has come out:
R. Koekoek and R.F. Swarttouw,
"The Askey scheme of hypergeometric orthogonal polynomials and its
q-analogue",
Report 94-05, Faculty of Technical Mathematics and Informatics,
Delft University of Technology, 120 pp.
For all classes of orthogonal polynomials fitting into the Askey
scheme or its q-analogue, the standard formulas are listed. Moreover,
a comprehensive list of limit formulas between the various classes is
given. The authors still consider this paper as a preliminary
version. They solicit comments from readers for improvement.
For ordering information please contact Roelof Koekoek
<koekoek@dutiaw3.tudelft.nl>. However, the report is temporarily out
of stock.
