ABSTRACT
Let α1, . . . , αn be any set of n positive integers. The problem is to find the smallest N such that, for any set of n distinct points z1, . . . , zn in the complex plane and α1 + · · · + αn arbitrarily prescribed values
w0,ν , . . . , wαν−1,ν (ν = 1, . . . , n) ,
there exists a polynomial p(z) := ∑N
ν=0 aν z ν of degree not exceeding
N satisfying
p(j)(z1) = wj,1 (j = 0, . . . , α1 − 1) . . .
