  "abstract": "The strange quark mass is calculated from QCD sum rules for the divergence of the vector as well as axial-vector current in the next-next-to-leading logarithmic approximation. The determination for the divergence of the axial-vector current is found to be unreliable due to large uncertainties in the hadronic parametrisation of the two-point function. From the sum rule for the divergence of the vector current, we obtain a value of $m_s\\equiv\\mb_s(1\\,\\gev)=189\\pm32\\,\\mev$, where the error is dominated by the unknown perturbative ${\\cal O}(\\alpha_s^3)$ correction. Assuming a continued geometric growth of the perturbation series, we find $m_s=178\\pm18\\,\\mev$. Using both determinations of $m_s$, together with quark-mass ratios from chiral perturbation theory, we also give estimates of the light quark masses $m_u$ and $m_d$.",
