摘要:
The problem of the limiting distribution of the zeros and the asymptotic behaviour of the Hermite-Pade polynomials of the first kind is considered for a system of germs [1, f(1,infinity),..., f(m,infinity)] of meromorphic functions f(j), j = 1,..., m, on an (m+1)-sheeted Riemann surface R. Nuttall's approach to the solution of this problem, based on a particular 'Nuttall' partition of R into sheets, is further developed.
