摘要
In some recent investigations involving differential operators for the generalized Lagrange polynomials, Chan et al. [W.-C.C. Chan, C.-J. Chyan, H.M. Srivastava, The Lagrange polynomials in several variables, Integral Transforms Spec. Funct. 12 (2001) 139-148] encountered and proved a certain summation identity for the Lagrange polynomials in several variables, which are popularly known in the literature as the Chan-Chyan-Srivastava polynomials. In the present paper, we investigate several families of bilateral generating functions for the Erku艧-Srivastava polynomials (which are more general than the Chan-Chyan-Srivastava polynomials) and the Srivastava-Daoust (or generalized Lauricella) functions.
