Shanks' convergence acceleration transform, Padé approximants and partitions
1986
Journal of combinatorial theory. Series A
Preserved Fulltext
Shanks developed a method for accelerating the convergence of sequences. When applied to classical sequences in number theory, Shanks' transform yields some famous identities of Euler and Gauss. ...
It is shown here that the Pad&. approximants for the little q-Jacobi polynomials can be used to explain and extend Shanks' observations. ...
We rely on the close relationship of Shanks' transform to Pade approximants [lo; p. 211, and reveal that the little q-Jacobi polynomials and the PadC approximants related to their moment generating function ...
