摘要：

Extremal properties and localization of zeros of general (including nondiagonal) type I Hermite–Padé polynomials are studied for the exponential system {eλjz}j=0k with arbitrary different complex numbers λ0, λ1,..., λk. The theorems proved in the paper complement and generalize the results obtained earlier by other authors.
