Pfaff's Method (III): Comparison With the WZ Method
George E. Andrews
Dedicated to my friend, Dominique Foata.
In the 1990's, the WZ method has been the method of choice in
resolving new conjectures for hypergeometric identities. The object
here is to compare the WZ method with Pfaff's method. Such a
comparison should (it is hoped) provide some suggestions for the
further development of each method.
