Isomorphism Problems and Groups of Automorphisms for Generalized Weyl Algebras
نویسندگان
چکیده
We present solutions to isomorphism problems for various generalized Weyl algebras, including deformations of type-A Kleinian singularities 14] and the algebras similar to U(sl 2) introduced in 31]. For the former, we generalize results of Dixmier 11, 12] on the rst Weyl algebra and the minimal primitive factors of U(sl 2) by nding sets of generators for the group of automorph-isms.

Weyl Group of Bn as Automorphisms of n-Cube: Isomorphism and Conjugacy
The Weyl groups are important for Lie algebras. Lie algebras arise in the study of Lie groups, coming from symmetries of differential equations, and of differentiable manifolds. The Weyl groups have been used to classify Lie algebras up to isomorphism. The Weyl group associated to a Lie algebra of type Bn and the group of graph automorphisms of the n-cube Aut(Qn) are known to be isomorphic to Z...
متن کاملAutomorphisms and Twisted Forms of Generalized Witt Lie Algebras
We prove that the automorphisms of the generalized Witt Lie algebras W(m , n) over arbitrary commutative rings of characteristic p > 3 all come from automorphisms of the algebras on which they are defined as derivations. By descent theory, this result then implies that if a Lie algebra over a field becomes isomorphic to W{m, n) over the algebraic closure, it is a derivation algebra of the type ...
متن کاملAutomorphisms of Verardi Groups: Small Upper Triangular Matrices over Rings
Verardi’s construction of special groups of prime exponent is generalized, and put into a context that helps to decide isomorphism problems and to determine the full group of automorphisms (or at least the corresponding orbit decomposition). The groups in question may be interpreted as groups of unitriangular matrices over suitable rings. Finiteness is not assumed.
متن کاملPositive Cone in $p$-Operator Projective Tensor Product of Fig`a-Talamanca-Herz Algebras
In this paper we define an order structure on the $p$-operator projective tensor product of Herz algebras and we show that the canonical isometric isomorphism between $A_p(Gtimes H)$ and $A_p(G)widehat{otimes}^p A_p(H)$ is an order isomorphism for amenable groups $G$ and $H$.

It is shown that every almost linear bijection $h : Arightarrow B$ of a unital $C^*$-algebra $A$ onto a unital$C^*$-algebra $B$ is a $C^*$-algebra isomorphism when $h(3^n u y) = h(3^n u) h(y)$ for allunitaries $u in A$, all $y in A$, and all $nin mathbb Z$, andthat almost linear continuous bijection $h : A rightarrow B$ of aunital $C^*$-algebra $A$ of real rank zero onto a unital$C^*$-algebra...
