alpha_s Determinations from Jets and Scaling Violations at HERA
Thomas Kluge (Desy, Germany)

A review is given on recent alpha_s determinations from the H1 and ZEUS Collaborations. These are based on measurements of jet cross sections as well as on the observed scaling violation of the structure function F2. A HERA average on alpha_s(m_Z) is presented, in comparison with world mean values.
