报告题目:

Fibered varieties over curves with low slope and sharp bounds in dimension three

报告摘要:

In this talk, I will introduce the optimal slope inequality for fibered threefolds over curves and an effective Cornalba-Harris-Xiao type slope inequality for families of surfaces of general type over curves. The construction of fibered threefolds with low slope will also be discussed. This is a joint work with Tong Zhang.
