- Title : The semi-positivity theorem and the generic p-rank for a
semi-stable fibration. - Speaker : Junmyeong Jang(Ulsan University) - Date & Time : 8 May , 2012 (TUE) 16:00~17:00 - Place : Math
Science Building room 208 - Abstract In this talk, we will see over a field of positive charactersitic, the semi-positivity theorem for a
semi-stable fibered surface is related to the p-rank. Using this result we will
construct a counterexample of the Miyaoka-Yau inequality with smooth Picard scheme. |
