Yong Hu, Noether-Severi Inequality and Equality for Irregular Threefolds of General Type

B266 IBS, Korea, Republic of

     Speaker Yong Hu KIAS For complex smooth irregular 3-folds of general type, I will introduce the optimal Noether-Severi inequality. This answers an open question of Zhi Jiang in dimension three. Moreover, I will also completely describe the canonical models of irregular 3-folds attaining the Noether-Severi equality. This is a joint work with Tong

Yong Hu, Noether Inequality for Irregular Threefolds of General Type

B236-1 IBS, Korea, Republic of

    Speaker Yong Hu Shanghai Jiao Tong University Let X be a smooth irregular 3-fold of general type. In this talk, we will prove that the optimal Noether inequality vol(X) ≥ (4/3) pg(X) holds if pg(X) ≥ 16 or if X has a Gorenstein minimal model. Moreover, when X attains the equality and pg(X)
