Inverse polynomial expansions of Laurent series. II
An algorithm is given, and shown to lead to various series expansions of formal Laurent series, as the sums of reciprocals of polynomials. The degrees of approximation by the rational functions which are the partial sums of these series are investigated. The types of series corresponding to rational functions themselves are also partially characterized. The first paper of this sequence appeared in Constructive Approximation 4, 379-389 (1988; Zbl 0659.41024).
