Structure theorem for projective klt pairs with nef anti-canonical divisor

Shin-ichi Matsumura, Juanyong Wang

In this paper, we establish a structure theorem for projective klt pairs $(X, Δ)$ with nef anti-log canonical divisor; specifically, we prove that, up to replacing $X$ with a finite…

Strictly nef divisors on K-trivial fourfolds

Haidong Liu, Shin-ichi Matsumura

In this paper, we prove the ampleness conjecture and Serrano's conjecture for strictly nef divisors on K-trivial fourfolds. Specifically, we show that any strictly nef divisors on…
