Quivers, Desingularizations and Canonical Bases
A class of desingularizations for orbit closures of representations of Dynkin quivers is constructed, which can be viewed as a graded analogue of the Springer resolution. A stratification of the
Characteristics cycles of toric varieties : perverse sheaves on rank stratifications
We present two calculations involving singularities of algebraic varieties. The first is a combinatorial algorithm to compute the characteristic cycle of a torus invariant sheaf on a toric variety.
Tensor product varieties, perverse sheaves, and stability conditions
The space spanned by the class of simple perverse sheaves in Zheng (2008) without localization is isomorphic to the tensor product of a Verma module with a tensor product of irreducible integrable
Almost-commuting variety, D-modules, and Cherednik algebras
We study a scheme M closely related to the set of pairs of n by n-matrices with rank 1 commutator. We show that M is a reduced complete intersection with n+1 irreducible components, which we
We realize the crystal associated to the quantized enveloping algebras with a symmetric generalized Cartan matrix as a set of Lagrangian subvarieties of the cotangent bundle of the quiver variety. As
Affine Lie algebras and tame quivers
Abstract. C.M. Ringel defined a Hall algebra associated with the category of representations of a quiver of Dynkin type and gave an explicit description of the structure constants of the
Quivers with loops and perverse sheaves
In this article we consider the general definition of Lusztig sheaves for arbitrary quivers, possibly carrying loops. We prove a conjecture raised by Lusztig asking if the more elementary Lusztig
Euler characteristic of quiver Grassmannians and Ringel-Hall algebras of string algebras
We compute the Euler characteristics of quiver Grassmannians and quiver flag varieties of tree and band modules and prove their positivity. This generalizes some results by G.C. Irelli
Lectures on perverse sheaves on instanton moduli spaces
I will explain my joint paper `Instantons moduli spaces and W-algebras' with A.Braverman, M.Finkelberg, arXiv:1406.2381. I will concentrate on the geometric part, that is a study of perverse sheaves

Canonical bases arising from quantized enveloping algebras
0.2. We are interested in the problem of constructing bases of U+ as a Q(v) vector space. One class of bases of U+ has been given in [DL]. We call them (or, rather, a slight modification of them, see
Hall algebras and quantum groups
The Hall algebra of a finitary category encodes its extension structure. The story starts from the work of Steinitz on the module category of an abelian p-group, where the Hall algebra is the algebra
