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…
Chern numbers of terminal threefolds
Paolo Cascini, Hsin-Ku Chen
Let X be a smooth threefold. We show that if is a flip which appears in the -MMP, then is bounded by a constant depend…
Minimal resolutions of threefolds
Hsin-Ku Chen
We describe the resolution of singularities of a threefold which has minimal Picard number. We describe the relation between this minimal resolution and an arbitrary resolution of…
On the factorization of three-dimensional terminal flops
Hsin-Ku Chen
We factorize three-dimensional terminal flops into a composition of divisorial contractions to points and blowing-up smooth curves.
On the Nash problem for terminal threefolds of type
Hsin-Ku Chen
We study Nash valuations and essential valuations of terminal threefolds of type . If or the given threefold is -factorial, then all the Nash valuations and…
Threefolds of Kodaira dimension one
Hsin-Ku Chen
We prove that for any smooth complex projective threefold of Kodaira dimension one, the -th pluricanonical map is birational to the Iitaka fibration for every and di…
Betti numbers in three dimensional minimal model program
Hsin-Ku Chen
Let be a smooth projective threefold. We prove that, among the process of minimal model program, the variance of the third Betti number can be bounded by some integer depends o…
