Facultad de Matemáticas Universidad Complutense de Madrid 28040 Madrid España e-mail: jmgamboa@eucmax.sim.ucm.es A note on cohomology over non algebraically closed fields [Elektronische Daten] [J.M. Gamboa] We characterise algebraically closed fields as those for which the first cohomology group H1(kn, On) of the sheaf On of regular functions over kn vanishes for all positive intergers n.
