This up to date version will proceed to satisfy the wishes for an authoritative entire research of the swiftly turning out to be box of uncomplicated hypergeometric sequence, or q-series. It contains deductive proofs, workouts, and helpful appendices. 3 new chapters were further to this variation overlaying q-series in and extra variables; linear- and bilinear-generating services for easy orthogonal polynomials; and summation and transformation formulation for elliptic hypergeometric sequence. additionally, the textual content and bibliography were increased to mirror fresh advancements. First version Hb (1990): 0-521-35049-2

2) which clearly approaches n! as q ---+ 1-. Hence f q(n + 1) tends to f( n + 1) = n! as q ---+ 1-. 1). 3) q---+I we shall give a simple, formal proof due to Gosper; see Andrews [1986]. 11]) and the well-known functional equation for the gamma function r(x + 1) = xr(x), r(1) = 1. 4) For a rigorous justification of the above steps see Koornwinder [1990]. 5) f(x + 1) = - 1 - f (x), f(l) = 1. 1) is a natural q-analogue of f(x). 1) that fq(x) has poles at x = 0, -1, -2, ....
