Positivity for Weil divisors

Tuesday, February 18, 2014 -
4:30pm to 5:30pm
We define and study positivity (nefness, amplitude, bigness and pseudo-effectiveness) for Weil divisors on normal projective varieties. We prove various characterizations, vanishing and non-vanishing theorems for cohomology, global generations statements, and a result related to log Fano. Joint work with S. Urbinati.
