Our goal here is to show that the Kleinian singularities are actually quo-tients of C2 by the action of finite subgroups of SL 2(C). First, let us recall some general properties of quotients under finite group actions. Let X be an affine algebraic variety and Γ be a group acting on X by automorphisms. Then Γ also

Webone of the following 5 groups. Proposition 2.3. (1) Cn(cyclic group of order n) (2) D˜ n (double cover of dihedral group) (3) T˜(double cover of tetrahedral group) (4) O˜ (double cover of binary octahedral Group) (5) I˜ (double cover of binary icosahedral group) We will denote Γ˜ to be a finite subgroup of SL(2,C). We are interested WebApr 29, 2024 · We survey various generalizations of braid groups for quivers with superpotential and focus on the cluster braid groups, which are introduced in a joint work with King (2024). Our motivations come from the study of cluster algebras, Calabi-Yau categories and Bridgeland stability conditions. Download to read the full article text … diffuser cushion aidacare

Webrepresentations, [L1, L2, KaS] for quantum groups, [AuR, CB] for Kleinian singularities, [N1, N2, N3] for quiver varieties, and [GLS1, GLS2] for cluster algebras. For the case of proprojective algebras of non-Dynkin type, its tilting theory has been extensively studied in [BIRS, IR1]. In particular, they show that certain ideals parameter- WebBraid groups and Kleinian singularities Brav, Christopher ; Thomas, Hugh We establish faithfulness of braid group actions generated by twists along an ADE configuration of … WebDec 24, 2010 · Braid groups and Kleinian singularities Christopher Brav & Hugh Thomas Mathematische Annalen 351 , 1005–1017 ( 2011) Cite this article 350 Accesses 24 Citations Metrics Abstract We establish faithfulness of braid group actions generated by twists … formula power query if
