WebIn the second part, we use this characterization to determine the generating functions of the Euler characteristics of the quiver Grassmannians (resp. F-polynomials). Along these lines, we obtain explicit formulae for all cluster variables of cluster algebras coming from quivers of type $\tilde D_{n}$ D ~ n . WebFor every tame quiver, there are singular quiver Grassmannians for representations in exceptional and homogeneous tubes (Theorem 2.12). There are flat families of quiver Grassmannians whose fibres have different isomorphism types, different Poincaré polynomials and different Euler characteristics (Example 2.10). how to cut foam cushion straight
[PDF] Quiver grassmannians, quiver varieties and the preprojective ...
WebQuivers play an important role in the representation theory of algebras, with a key ingredient being the path algebra and the preprojective algebra. Quiver grassmannians are varieties of submodules of a fixed module of the path or preprojective algebra. In the current paper, we study these objects in detail. We show that the quiver grassmannians corresponding to … WebThe Internet Archive offers over 20,000,000 freely downloadable books and texts.
