Post-Lie algebra structures for perfect Lie algebras. [PDF]

open access: yesCommun Algebra, 2023
We study the existence of post-Lie algebra structures on pairs of Lie algebras (g,n), where one of the algebras is perfect non-semisimple, and the other one is abelian, nilpotent non-abelian, solvable non-nilpotent, simple, semisimple non-simple ...

Post-Lie algebra structures for nilpotent Lie algebras [PDF]

open access: yesInternational Journal of Algebra and Computation, 2018
We study post-Lie algebra structures on [Formula: see text] for nilpotent Lie algebras. First, we show that if [Formula: see text] is nilpotent such that [Formula: see text], then also [Formula: see text] must be nilpotent, of bounded class. For post-Lie

On the Lie Enveloping Algebra of a Post-Lie Algebra

open access: yesJournal of Lie Theory, 2014
We consider pairs of Lie algebras $g$ and $\bar{g}$, defined over a common vector space, where the Lie brackets of $g$ and $\bar{g}$ are related via a post-Lie algebra structure. The latter can be extended to the Lie enveloping algebra $U(g)$.

Isomorphism of Intransitive Linear Lie Equations [PDF]

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2009
We show that formal isomorphism of intransitive linear Lie equations along transversal to the orbits can be extended to neighborhoods of these transversal. In analytic cases, the word formal is dropped from theorems.

Dual formulation of the Lie algebra S-expansion procedure [PDF]

open access: yesJournal of Mathematical Physics, 2009
The expansion of a Lie algebra entails finding a new bigger algebra G through a series of well-defined steps from an original Lie algebra g. One incarnation of the method, the so-called S-expansion, involves the use of a finite Abelian semigroup S to ...

Quantum scars as embeddings of weakly broken Lie algebra representations [PDF]

open access: yesPhysical review B, 2020
Recently, much effort has focused on understanding weak ergodicity breaking in many-body quantum systems that could lead to wavefunction revivals in their dynamics far from equilibrium.

Lie-Algebra of Single-Valued Pentapartitioned Neutrosophic Set [PDF]

open access: yesNeutrosophic Sets and Systems, 2022
In this article, we procure the concept of single-valued pentapartitioned neutrosophic Lie (in short SVPN-Lie) algebra under single-valued pentapartitioned neutrosophic set (in short SVPN-set) environment.

A Left-Symmetric Structure on The Semi-Direct Sum Real Frobenius Lie Algebra of Dimension 8

open access: yesCauchy: Jurnal Matematika Murni dan Aplikasi, 2022
Let  be the Lie algebra of  the semi-direct sum of the real vector space   and the Lie algebra  of the sets of all  real matrices. In this paper, a Frobenius functional is constructed in order for the Lie algebra  to be the real Frobenius Lie algebra of ...
