| Abstract: | Here we prove in positive characteristic the spannedness or very ampleness or k-ampleness of the adjuntion bundle KS⊕L with S surface of Kodaira dimension ≤0 L∈Pic(S), L ample, under numerical conditions on L which are similar to the ones
required in characteristic 0 by Reider method. |
