• In this paper, we are concerned with the relation between the ordinarity of surfaces of general type and the failure of the BMY-inequality in positive characteristic. We consider semistable fibrations $\pi:S \longrightarrow C$ where $S$ is a smooth projective surface and $C$ is a smooth projective curve. Using the exact sequence relating the locally exact differential forms on $S$, $C$, and $S/C$ (Section 3), we prove in Section 4 an inequality relating $c_1^2$ and $c_2$ for ordinary surfaces… CONTINUE READING
