View PDF Abstract: Given a quiver with potential $(Q,W)$, Kontsevich-Soibelman constructed a Hall algebra on the cohomology of the stack of representations of $(Q,W)$. As shown by Davison-Meinhardt, this algebra comes with a filtration .2 TUDOR PADURARIU˘ algebra (HA) of (Q,W). Its K0 is called the K-theoretic Hall algebra (KHA) of (Q,W). For any edge e∈E, let C∗ act on R(d) by scaling the linear map corresponding to e. Let (C∗)E be the product of these multiplicative groups. One can consider a graded version of Hall algebras HAgr(Q,W) for any group C∗ ⊂(C∗)E scaling TrWwith weight 2.

Abstract: I will explain some results in categorical Donaldson-Thomas theory of C 3. An important construction is that of quasi-BPS categories, which are a categorical approximation of BPS (also called Gopakumar-Vafa) invariants in enumerative geometry.

TUDOR PADURARIU˘ Abstract. For a large class of good moduli spaces X of symmetric stacks X, we define noncommutative motives Dnc(X) which can be regarded as categori-fications of the intersection cohomology of X. These motives are summands of noncommutative resolutions of singularities D(X) ⊂ Db(X) of X. The category Speaker: Tudor Pădurariu (Columbia University) Title: Relative stable pairs and a non-Calabi-Yau wall crossing. Abstract: For complex smooth threefolds, there are enumerative theories of curves defined using sheaves, such as Donaldson-Thomas (DT) theory using ideal sheaves and Pandharipande-Thomas (PT) theory using stable pairs.TUDOR PADURARIU˘ Abstract. Given a quiver with potential (Q,W), Kontsevich–Soibelman con-structed a Hall algebra on the critical cohomology of the stack of representations of (Q,W). Special cases of this construction are related to work of Nakajima, Varagnolo, Schiffmann–Vasserot, Maulik–Okounkov, Yang–Zhao etc. about geo-Author ID: padurariu.tudor.
