Invariance of plurigenera for generalized polarized pairs with abundant nef parts

Zhan Li, Zhiwei Wang

We show the invariance of plurigenera for generalized polarized pairs with abundant nef parts and generalized canonical singularities. This is obtained by investigating a type of n…

On the relative Morrison-Kawamata cone conjecture

Zhan Li, Hang Zhao

We relate the Morrison-Kawamata cone conjecture for Calabi-Yau fiber spaces to the existence of Shokurov polytopes. For K3 fibrations, the existence of (weak) fundamental domains f…

A variant of the effective adjunction conjecture with applications

Zhan Li

We propose a variant of the effective adjunction conjecture for lc-trivial fibrations. This variant is suitable for inductions and can be used to treat real coefficients.

On finiteness of log canonical models

Zhan Li

Let be klt pairs and be a convex set of divisors. Assuming that the relative Kodaira dimensions are non-negative, then there are only finitely many log canonical mod…

Boundedness of the base varieties of certain fibrations

Zhan Li

It is conjectured that the base varieties of the Iitaka fibrations are bounded when the Iitaka volumes are bounded above. We confirm this conjecture for Iitaka -lc Fano type fib…

On accumulation points of pseudo-effective thresholds

Jingjun Han, Zhan Li

We characterize a -th accumulation point of pseudo-effective thresholds of -dimensional varieties as certain invariant associates to a numerically trivial pair of an -…

Weak Zariski decompositions and log terminal models for generalized polarized pairs

Jingjun Han, Zhan Li

We show that the existence of a birational weak Zariski decomposition for a pseudo-effective generalized polarized lc pair is equivalent to the existence of a generalized polarized…

On Fujita's conjecture for pseudo-effective thresholds

Jingjun Han, Zhan Li

We show Fujita's spectrum conjecture for -log canonical pairs and Fujita's log spectrum conjecture for log canonical pairs. Then, we generalize the pseudo-effective threshold of…

ACC for log canonical threshold polytopes

Jingjun Han, Zhan Li, Lu Qi

We show that the log canonical threshold polytopes of varieties with log canonical singularities satisfy the ascending chain condition.

On derived equivalence of general Clifford double mirrors

Zhan Li

We show that general Clifford double mirrors constructed in "On Clifford double mirrors of toric complete intersections" are derived equivalent.

On Clifford double mirrors of toric complete intersections

Lev Borisov, Zhan Li

We present a construction of noncommutative double mirrors to complete intersections in toric varieties. This construction unifies existing sporadic examples and explains the under…
