Description

Sister Celine's algorithm computes "k-free" recurrences for hypergeometric terms and sums.

http://mathworld.wolfram.com/SisterCelinesMethod.html

Add these functions:

  • to verify that a term is hypergeometric
  • to find recurrence for the summand
  • to sum over the recurrence found above

Hi Karen, the Author: trac ticket field specifies the author of the code (if such is present). If you only want to report the ticket your authorship is specified in the Reported by: field automatically.

In other words, the fact that you wrote "Karen Kohl" as Author implies to me that you are actually going to work on this ticket.
