Multivariate Padé approximation. (English) Zbl 1090.41505
The paper represents a survey of some new results on the multivariate Padé approximation. Two groups of multivariate Padé approximants are discussed: approximants of f/g with g as a polynomial and approximants of f/g with g as a holomorphic function. An open question is formulated.
