Log Calabi--Yau structure for endomorphisms on

Yujie Luo, Sheng Meng

Let be a -polarized endomorphism, where , and let be its ramification divisor. We study the singularities of the ramification pair $(\…

Sharp Bounds for Totally Invariant Cycles of Projective Varieties

Wentao Chang, Yujie Luo

The paper establishes explicit bounds on the total degree of prime cycles that become totally invariant under iterates of an int‑amplified endomorphism on smooth projective varieti…

Galois self-covers of projective spaces and essential dimensions

Yujie Luo, De-Qi Zhang

We give the structure theorem of Galois self-covers . As an application, we show that the essential dimension of every such nontrivial cover attai…

Essential dimensions of polarized endomorphisms of certain algebraic surfaces

Qianli Fang, Yujie Luo, De-Qi Zhang

Let be a polarized endomorphism of a smooth projective surface which is birationally ruled. We answer a question of Kollár and Zhuang, in the affirmative, on the inco…

Jordan property for automorphism groups of compact varieties

Yujie Luo, Sheng Meng, De-Qi Zhang

In this note, we report some recent progress on the Jordan property for (birational) automorphism groups of projective varieties and compact complex varieties.
