Title: On the dimension of spaces of linear transformations with constant rank and uniform vector bundles
Time&Venue: 2024年10月23日（周三） 13：30-14：30 思源楼 817
Abstract: I will talk about the relation between the dimension of spaces of linear transformations with constant rank and uniform vector bundles on projective spaces.
Some conjectures and partial results will also be discussed on this object. This talk is from a joint work with Yuhang Zhou.

Title: Moduli spaces of threefolds on the Noether line
Abstract: I will talk about the classification of canonical threefolds on the Noether line by describing their moduli spaces, which includes an explicit stratification, an estimate of the number of irreducible components and the dimension formula for every such moduli space. I will also discuss the key idea behind the proof, which is to relate canonical threefolds on the Noether line to simple fibrations in (1,2)-surfaces. This is a joint work with S. Coughlan, Y. Hu and R. Pignatelli.
