Characterization of Lie-Type Higher Derivations of von Neumann Algebras with Local Actions

open access: yesMathematics, 2023
Let m and n be fixed positive integers. Suppose that A is a von Neumann algebra with no central summands of type I1, and Lm:A→A is a Lie-type higher derivation.

Nonlinear Lie Triple Higher Derivations on Triangular Algebras by Local Actions: A New Perspective

open access: yesAxioms, 2022
Let R be a commutative ring with unity and T be a triangular algebra over R. Let a sequence Δ={δn}n∈N of nonlinear mappings δn:T→T is a Lie triple higher derivation by local actions satisfying the equation.

Lie algebras of vertical derivations on semiaffine varieties with torus actions [PDF]

open access: yesJournal of Pure and Applied Algebra, 2021
Let X be a normal variety endowed with an algebraic torus action. An additive group action $ $ on X is called vertical if a general orbit of $ $ is contained in the closure of an orbit of the torus action and the image of the torus normalizes the image of $ $ in Aut(X).

Sextonians and the magic square [PDF]

open access: yes, 2004
Associated to any complex simple Lie algebra is a non-reductive complex Lie algebra which we call the intermediate Lie algebra. We propose that these algebras can be included in both the magic square and the magic triangle to give an additional row and ...

An inner automorphism is only an inner automorphism, but an inner endomorphism can be something strange [PDF]

open access: yes, 2011
The inner automorphisms of a group G can be characterized within the category of groups without reference to group elements: they are precisely those automorphisms of G that can be extended, in a functorial manner, to all groups H given with ...

\'Etale Descent of Derivations [PDF]

open access: yes, 2013
We study \'etale descent of derivations of algebras with values in a module. The algebras under consideration are twisted forms of algebras over rings, and apply to all classes of algebras, notably associative and Lie algebras, such as the multiloop ...

Derivations of the Moyal Algebra and Noncommutative Gauge Theories [PDF]

open access: yes, 2008
The differential calculus based on the derivations of an associative algebra underlies most of the noncommutative field theories considered so far. We review the essential properties of this framework and the main features of noncommutative connections ...

Existentially closed fields with G-derivations [PDF]

open access: yes, 2015
We prove that the theories of fields with Hasse-Schmidt derivations corresponding to actions of formal groups admit model companions. We also give geometric axiomatizations of these model companions.Comment: In version 2: new proof of (the current ...

The irreducible modules for the derivations of the rational quantum torus

open access: yes, 2014
Let $\bbcq$ be the quantum torus associated with the $d \times d$ matrix $q = (q_{ij})$, $q_{ii} = 1$, $q_{ij}^{-1} = q_{ji}$, $q_{ij}$ are roots of unity, for all $1 \leq i, j \leq d.$ Let $\Der(\bbcq)$ be the Lie algebra of all the derivations of ...

Representations of Homotopy Lie-Rinehart Algebras

open access: yes, 2014
I propose a definition of left/right connection along a strong homotopy Lie-Rinehart algebra. This allows me to generalize simultaneously representations up to homotopy of Lie algebroids and actions of strong homotopy Lie algebras on graded manifolds.
