Title:
 An example of liftings with different Hodge numbers
Time & Venue:
 2019.8.22 9:20-10:20 N213
Abstract:
 Does a smooth proper variety in positive characteristic know the Hodge number of its liftings? The answer is ”of course not”. However, it’s not that easy to come up with a counter-example. In this talk, I will first introduce the background of this problem. Then I shall discuss some obvious constraints of constructing a counter-example. Lastly I will present such a counter-example and state a further question.
