D. dissertation of Sister Mary Celine Fasenmyer, in 1945. It showed how recurrences for certain polynomial sequences could be found algorithmically. ) • [Gosp78], by R. W. , is the discovery of the algorithmic solution of the problem of indefinite hypergeometric summation (see Chapter 5). Such a summation is of the form f (n) = nk=0 F (k), where F is hypergeometric. • [Zeil82], of Zeilberger, recognized that Sister Celine’s method would also be the basis for proving combinatorial identities by recurrence.

In this chapter we have seen how to take a sum and identify it, when possible, as a standard hypergeometric sum. We have also seen a list of many of the important hypergeometric sums that can be expressed in simple, closed form.
K, 0, n}], we find that Mathematica is very well trained indeed, since it gives LaguerreL[n, 0, 1] which means that it recognizes our sum as a Laguerre polynomial! The trick of inserting xk won’t change this behavior, so there isn’t any way to adapt this routine to the present example. ) and then ask for3 the term ratio, FactorialSimplify[t[k+1]/t[k]]. We would obtain the term ratio in the nicely factored form k−n . 4, −n ;1 . 1F1 1 3 Read in DiscreteMath‘RSolve‘ before attempting to FactorialSimplify something.
