Abstract

The author presents here a systematic analysis of certain bilinear and bilateral generating relations associated with the generalized Laguerre polynomials {Ln (a) (x)} defined by

$$(1 - t)^{ - 1 - \alpha } \exp \left( { - \frac{{xt}}{{1 - t}}} \right) = \sum\limits_{n = 0}^\infty {L_n ^{(\alpha )} (x) t^n .} $$

It is observed that the four formulas proved recently by Jain [7] are only specialized or limiting forms of the results of Erdélyi,[4] Meixner [8] and the author [12–14].
