Topic #8 ---------------- OP-SF NET --------------- March 16, 1994 ~~~~~~~~~ From: George Gasper Subject: Russian translation of book by Gasper & Rahman The Russian translation (by N.M. Atakishiyev and S.K. Suslov) of the G. Gasper and M. Rahman 1990 book "Basic Hypergeometric Series" has just been published by MIR and may be obtained from MIR at a very low cost in Russia. Topic #9 ---------------- OP-SF NET --------------- March 16, 1994 ~~~~~~~~~ From: Christian Krattenthaler (slightly edited) Subject: Mathematica packages HYP and HYPQ Christian Krattenthaler has developed a couple of Mathematica packages, called HYP and HYPQ. The first is for the manipulation of binomial and hypergeometric series, while the second deals with q-binomial and basic hypergeometric series. New versions have now become available. In detail, HYP provides tools for: (A) manipulating factorial expressions (B) transforming binomial sums into hypergeometric notation (C) summing hypergeometric series (D) transforming hypergeometric series (E) applying contiguous relations (F) doing formal limits of hypergeometric expressions (G) transforming hypergeometric expressions into TeX-code (H) Using the Gosper and Zeilberger algorithms HYPQ provides tools for analogous work with q-factorials, q-binomials, q-hypergeometric series, etc. The packages are available by anonymous ftp from pap.univie.ac.at in directory MATHEMATICA.HYP_HYPQ There is a read.me file available for further instructions. If you have any questions, problems, suggestions,... please contact Christian Krattenthaler . Topic #10 --------------- OP-SF NET --------------- March 16, 1994 ~~~~~~~~~ From: Peter Paule Subject: Mathematica packages of Gosper's and Zeilberger's algorithms Mathematica packages of Gosper's and Zeilberger's algorithms, implemented by P. Paule and M. Schorn, are available by email-request to Peter Paule . When these packages are installed, one can either work directly with them under Mathematica, or call them by a procedure in the HYP or HYPQ package (see previous topic). Topic #11 --------------- OP-SF NET --------------- March 16, 1994 ~~~~~~~~~ From: Waleed A. Al-Salam Subject: Anonymous ftp site on Orthogonal Polynomials etc. Waleed Al-Salam has an anonymous ftp site at euler.math.ualberta.ca on orthogonal polynomials and related special functions.
