Abstract: Gelfond and Khovanskii found a formula for the sum of the values of a Laurent polynomial over the zeros of a system of $ n$ Laurent polynomials in $ (\mathbb{C}\setminus 0)^n$. We expect that a similar formula holds in the case of exponential sums with real frequencies. Here we prove such a formula in dimension one.
