An inequality of Frank, Steinmetz and Weissenborn
An inequality proved by Frank, Steinmetz and Weissenborn relates the frequency of poles of a function meromorphic in the plane to the frequency of zeros of a linear differential polynomial in that function with small coefficients. A version of this inequality is established in terms of the frequency of distinct zeros of the linear differential polynomial.
