By extending Dzyadyk’s method of generalized moment representations to the case of two-dimensional number sequences, we construct and study Padé approximants for some confluent Humbert hypergeometric series.
Two-Dimensional Generalized Moment Representations and Rational Approximations of Functions of Two Variables
Ukr. Mat. Zh. - 2013. - 65, № 8. - pp. 1035–1058
The Dzyadyk method of generalized moment representations is extended to the case of two-dimensional sequences and used to construct Padé approximants for functions of two variables.
