Jinhyung Park, Comparing Numerical Iitaka Dimensions

August 12, 2021 @ 11:00 am - 12:00 pm KST



Jinhyung Park
Sogang University

There are several definitions of the “numerical” Iitaka dimensions of a pseudoeffective divisor, which are numerical analogues to the Iitaka dimension. Recently, Lesieutre proved that notions of numerical Iitaka dimensions do not coincide. In this talk, we prove that many of numerical Iitaka dimensions are equal to the notion introduced by Boucksom-Demailly-Paun-Peternell and that some other invariants introduced by Nakayama and Lehmann can be arbitrarily larger than this notion. We also show some properties of abundant divisors. This is joint work with Sung Rak Choi.
