On the Kawaguchi--Silverman Conjecture for birational automorphisms of irregular varieties
Jungkai Alfred Chen, Hsueh-Yung Lin, Keiji Oguiso
We study the main open parts of the Kawaguchi--Silverman Conjecture, asserting that for a birational self-map of a smooth projective variety defined over $\overline{\mathbb…

On the divisorial contractions to curves of threefolds
Hsin-Ku Chen, Jheng-Jie Chen, Jungkai A. Chen
We prove that each divisorial contraction to a curve between terminal threefolds is a weighted blow-up under a suitable embedding. Moreover, we give a classification of the weighte…
