“…However, 2 F 1 (a, b; c; x) can be evaluated for parameter values satisfying certain conditions. For instance, Most of these identities have been derived using Gosper's algorithm, the W-Z method, Zeilberger's algorithm (see [8] and [9]), and the method of contiguity relations, which was recently introduced in [2]. In [2], a number of identities for 2 F 1 (a, b; c; x) are tabulated (see also [3], [5] and [6]).…”
