KW-sections for exceptional type Vinberg's $θ$ -groups

Paul Levy

Let $k$ be an algebraically closed field of characteristic not equal to 2 or 3, let $G$ be an almost simple algebraic group of type $F_{4}$ , $G_{2}$ or $D_{4}$ and let $θ$ be an automorp…

Isomorphism Problems of Noncommutative Deformations of Type D Kleinian Singularities

Paul Levy

We construct all possible noncommutative deformations of a Kleinian singularity $C^{2} /Γ$ of type $D_{n}$ in terms of generators and relations, and solve the problem of when…

Varieties of Modules for Z/2Z x Z/2Z

Paul Levy

Let $k$ be an algebraically closed field of characteristic 2. We prove that the restricted nilpotent commuting variety $C$ , that is the set of pairs of $(n \times n)$ -mat…

Involutions of reductive Lie algebras in positive characteristic

Paul Levy

Let $G$ be a reductive group over a field $k$ of characteristic $\neq = 2$ , let ${\mathfrak g}=\Lie(G)$, let $θ$ be an involutive automorphism of $G$ and let ${\mathfrak g}={\mathfra…
