Certain Examples of Deformed Preprojective Algebras and Geometry of Their *-representations

چکیده
We consider algebras eiΠ λ(Q)ei obtained from deformed preprojective algebra of affine type Π(Q) and an idempotent ei for certain concrete value of the vector λ which corresponds to the traces of −1 ∈ SU(2,C) in irreducible representations of finite subgroups of SU(2,C). We give a certain realization of these algebras which allows us to construct the C∗-enveloping algebras for them. Some well-known results, including description of four projections with sum 2 happen to be a particular case of this picture.

Central Extensions of Preprojective Algebras, the Quantum Heisenberg Algebra, and 2-dimensional Complex Reflection Groups
Preprojective algebras of quivers were introduced in 1979 by Gelfand and Ponomarev [GP], because for quivers of finite ADE type, they are models for indecomposable representations (they contain each indecomposable exactly once). Twenty years later, these algebras and their deformed versions introduced in [CBH] (for arbitrary quivers) became a subject of intense interest, since their representat...

In this paper we show that the moduli spaces of representations associated to the deformed multiplicative preprojective algebras recently introduced by Crawley-Boevey and Shaw carry a natural Poisson structure. This follows the fact that appropriately localized path algebras of double quivers carry a certain kind of non-commutative quasi-Hamiltonian structure.

We define and investigate deformed n-Calabi-Yau completions of homologically smooth differential graded (=dg) categories. Important examples are: deformed preprojective algebras of connected non Dynkin quivers, Ginzburg dg algebras associated to quivers with potentials and dg categories associated to the category of coherent sheaves on the canonical bundle of a smooth variety. We show that defo...
متن کاملLecture 16: Representations of Quivers
Now we proceed to study representations of quivers. We start by recalling some basic definitions and constructions such as the path algebra and indecomposable representations. Then we state a theorem of Kac that describes the dimensions, where the indecomposable representations occur as well as the number of parameters needed to describe their isomorphism classes. We will prove the Kac theorem ...
متن کاملNecklace Lie Algebras and Noncommutative Symplectic Geometry
Recently, V. Ginzburg proved that Calogero phase space is a coadjoint orbit for some infinite dimensional Lie algebra coming from noncommutative symplectic geometry, [12]. In this note we generalize his argument to specific quotient varieties of representations of (deformed) preprojective algebras. This result was also obtained independently by V. Ginzburg [13]. Using results of W. Crawley-Boev...
