Popis:	In this note we introduce exact sequences of sheaves on a complete smooth K ⁎ -surface without elliptic points. These sequences are an attempt to generalize the Euler sequence for a toric variety to complexity one surfaces. As an application we show that such a surface is rigid if and only if it is Fano.
