Abstract:
In this note, we prove that the syzygy bundle $M_L$ is cohomologically stable with respect to $L$ for any ample and globally generated line bundle $L$ on an Enriques (resp. bielliptic) surface over an algebraically closed field of characteristic $\neq 2$ (resp. $\neq 2,3$). In particular our result on complex Enriques surfaces improves the result of Torres-López and Zamora [Beitr. Algebra Geom. (2021)] (Corollary 3.5) by removing the condition on Clifford index. Together with the results of Camere [Math. Z 271 (2012), pp. 499–507] and Caucci–Lahoz [Bull. Lond. Math. Soc. 53 (2021), pp. 1030–1036], it implies that $M_L$ is stable with respect to $L$ for an ample and globally generated line bundle $L$ on any smooth minimal complex projective surface $X$ of Kodaira dimension zero.References
