Description (last modified by rws)

This is a metaticket listing existing functions for which symbolic implementations are urgently needed because

  • they exist in Sympy, Maxima, or Fricas symbolically, and might be returned as result
  • they belong to the holonomic repertoire

special:

  • Airy functions (#12455)
  • Kummer confluent hypergeometric functions (#14896)
  • spherical Bessel and Hankel functions (#15024)

combinatorial:

  • Bell numbers
  • Bernoulli numbers
  • Catalan numbers (#22028)
  • Fibonacci(n) (#22569), general Lucas(u,v)
  • rising/falling/subfactorial (#19461)

polynomial (metaticket #16670):

Also the Dirichlet Eta function (#22146) which however is not holonomic.
