On complex surfaces with 5 or 6 semistable singular fibers over P^1
Sheng-Li Tan, Yuping Tu, Alexis G. Zamora
Let be a fibered surface with fibers of genus g>1. If f is semistable and non isotrivial we prove that X of non negative Kodaira dimension implies that the number…
Effective behavior of multiple linear systems
Sheng-Li Tan
We give optimal effective bounds for some well-known theorems on complex algebraic surfaces, which are respectively due to Serre, Zariski (1962), Castelnuovo (1897), Artin (1962, 1…
The determination of integral closures and geometric applications
Sheng-Li Tan, De-Qi Zhang
We express explicitly the integral closures of some ring extensions; this is done for all Bring-Jerrard extensions of any degree as well as for all general extensions of degree < 6…
Families of K3 surfaces over curves satisfying the equality of Arakelov-Yau's type and modularity
Xiaotao Sun, Sheng-Li Tan, Kang Zuo
Let be a family of semistable K3 surfaces with non-empty set of singular fibres having infinite local monodromy. Then, when the so called Arakelov-Yau inequality rea…
