Abstract

© 2020 by the Mathematical Association of Thailand. We consider row sequences of three generalized Hermite-Padé approximations (orthogonal Hermite-Padé approximation, Hermite-Padé-Faber approximation, and multipoint Hermite-Padé approximation) of a vector of the approximated functions F and prove that if F has a system pole of order v, then such system pole attracts at least v zeros of denominators of these approximants at the rate of a geometric progression. Moreover, the rates of these attractions are estimated.
