SUMMARY:The extension of numerically trivial divisors on a family.
DESCRIPTION:Speaker: Lingyao Xie\, UCSD\n\nFor a projective morphism f: X to S, we explore when it is possible to extend a divisor that is numerically trivial over an open subset to a global relatively num-trivial divisor. In particular, we show that such $L$ always exists after a (weak) semi-stable reduction when $\dim S=1$. On the other …
