Pencils on Surfaces with Normal Crossings and the Kodaira Dimension of $\overline {\mathcal {M}}_{g,n}$
We study smoothing of pencils of curves on surfaces with normal crossings. As a consequence we show that the canonical divisor of $\overline {\mathcal {M}}_{g,n}$ is not pseudoeffective in some range, implying that $\overline {\mathcal {M}}_{12,6}$, $\overline {\mathcal {M}}_{12,7}$, $\overline {\ma...
