On supported deformations and birational isotriviality
On supported deformations and birational isotriviality
Let $f\colon X\to B$ be a semistable fibration with fibers of general type. We prove that if the general Kodaira-Spencer class is supported on the divisorial fixed part $D$ of a line bundle in $\Omega^k_X$, then, under natural conditions on $D$, the general fibers are birational.
