Abstract

We demonstrate by using the theory of order stars that analytic properties of complex functions impose bounds on the maximal block size in their Padé tableau. After a short survey of the relevant parts of order star theory we sketch the proofs of three theorems that provide realistic upper bounds on the block size in terms of zeros and essential singularities of the underlying function. These theorems are applied to investigate the structure of Padé tableaux of Jν, the Bessel function, and Eα, the Mittag-Leffler function.
