Abstract : Given n complex numbers, of which at least one has modulus not less than unity, it is shown that for at least one k, where k is less than or equal to n and more than or equal to 1, the sum of the kth powers of these numbers exceeds 1/3. This improves on earlier estimates of 1/6, or 1/5 for n greater than 8 pi. The problem has an application to the numerical solution of algebraic equations. (Author)
