Some Recent Progress on Serrano's Conjecture

2022-05-11 09:00-10:00 ZOOM

Abstract:
The positivity (nefness, strict nefness, ampleness) of divisors plays an important role in birational geometry. It is well-known that strictly nef divisors are not necessarily ample. However, Serrano's conjecture predicts that a small deformation of a strictly nef divisor in the direction of the canonical divisor is ample. In this talk, I will survey some recent progress on this conjecture. Part of my works are joint with Roberto Svaldi, Part of them are joint with Shin-ichi Matsumura.
