An Action of a Lie Algebra on the Homology Groups of Moduli Spaces of Stable Sheaves
نویسنده
چکیده
We construct an action of a Lie algebra on the homology groups of moduli spaces of stable sheaves on K3 surfaces under some technical conditions. This is a generalization of Nakajima’s construction of sl2-action on the homology groups [N6]. In particular, for an A, D, E-configulation of (−2)-curves, we shall give a collection of moduli spaces such that the associated Lie algebra acts on their homology groups.

Graph Homology: Koszul and Verdier Duality
We show that Verdier duality for certain sheaves on the moduli spaces of graphs associated to Koszul operads corresponds to Koszul duality of operads. This in particular gives a conceptual explanation of the appearance of graph cohomology of both the commutative and Lie types in computations of the cohomology of the outer automorphism group of a free group. Another consequence is an explicit co...
متن کاملMoyal quantization and stable homology of necklace Lie algebras
We compute the stable homology of necklace Lie algebras associated with quivers and give a construction of stable homology classes from certain A∞-categories. Our construction is a generalization of the construction of homology classes of moduli spaces of curves due to M. Kontsevich. In the second part of the paper we produce a Moyal-type quantization of the symmetric algebra of a necklace Lie ...
متن کاملModuli of Bridgeland semistable objects on P
Let X be a smooth projective surface, Coh(X) the abelian category of coherent sheaves on X, and D(X) the bounded derived category of coherent sheaves on X. We study the Bridgeland stability conditions on D(X) and see that for some stability conditions on D(X) the moduli spaces of (semi)stable objects in D(X) coincide with the moduli spaces of (semi)stable coherent sheaves, while for some other ...
متن کاملHeisenberg Algebra and Hilbert Schemes of Points on Projective Surfaces
The purpose of this paper is to throw a bridge between two seemingly unrelated subjects. One is the Hilbert scheme of points on projective surfaces, which has been intensively studied by various people (see e.g., [I, ES, Gö1, Gö2]). The other is the infinite dimensional Heisenberg algebra which is closely related to affine Lie algebras (see e.g., [K]). We shall construct a representation of the...
متن کاملFiber bundles and Lie algebras of top spaces
In this paper, by using of Frobenius theorem a relation between Lie subalgebras of the Lie algebra of a top space T and Lie subgroups of T(as a Lie group) is determined. As a result we can consider these spaces by their Lie algebras. We show that a top space with the finite number of identity elements is a C^{∞} principal fiber bundle, by this method we can characterize top spaces.
