Abstract: We will present the state of art of several homological conjectures related to Hochschild cohomology.

Title： A survey of shafarevich conjecture for hyperkahler varieties.
Speaker:李志远（上海数学中心）
Time：2020年9月10日
Tencent Meeting ID: 482 979 007
Abstract: The classical Shafarevich conjecture is about thefiniteness of isomorphism classes of varieties with good reduction over numberfields. In higher dimension case, Andre had verified the conjecture for verypolarized hyperkahler varieties. In this talk, I will survey the recentprogress for unpolarized hyper-Kahler varieties of arbitrary dimension.

Title： Basepoint-freeness of primitivepolarizations on Abelian varieties
Speaker:江智（上海数学中心）
Time：2020年9月17日
Tencent Meeting ID:106 321 103
Abstract:Fujita’s basepoint-freeness conjecture remains open in dimension >5. We will discuss some refined version of Fujita type equation on abelian varieties.
Talk4：
Title：GL_2(Q_p)-ordinary families and automorphy lifting
Speaker:丁一文（北京国际数学中心）
Time：2020年9月24日
Tencent Meeting ID:106 321 103
Abstract:Using Emerton’s parabolic ordinary part functor and p-adic local Langlands correspondence for GL_2(Q_p), we construct some families of p-adic automorphic representations, that we call GL_2(Q_p)-ordinary families. We will give some basic properties of these families and will report an “R=T” result on these families.

2020年10月22日 胡永泉（晨兴数学中心）
Title: Gelfand-Kirillov dimensions in p-adic Langlands program
Abstract: The Gelfand-Kirillov dimension is an important notion in the study of non-commutative noetherian rings. In this talk, I will first explain this notion for mod p and p-adic representations of p-adic groups, and then explain a control theorem of the Gelfand-Kirillov dimension for mod p representations of GL_2 and its application in the p-adic Langlands program. This is a joint work with Breuil, Herzig, Morra, Schraen, and with Wang.

Title: Localized characteristic classes for constructible etale sheaves
Abstract: In this talk, I will first recall the theory of singular support of constructible etale sheaves after Beilinson, and then define a localized version of characteristic class, which generalize Abbes- Saito’s definition. I will also show a relationship between the localized characteristic class and the relative characteristic class. This is joint work with Yigeng Zhao in progress.
