Homogeneous Lorentzian structures of 4-dimensional nilpotent Lie groups

Annales Polonici Mathematici, 2023
The authors consider one of the two nonabelian simply connected nilpotent Lie groups of dimension 4, the Lie group \(H_3(\mathbb{R}) \oplus \mathbb R\) (where \(H_3(\mathbb R)\) is the three-dimensional nilpotent Lie group). For this Lie group, the classification of left-invariant Lorentz metrics is known: there are two parametric families and three ...

Classification of Algebraic Schouten Solitons on Lorentzian Lie Groups Associated with the Perturbed Canonical Connection and the Perturbed Kobayashi-Nomizu Connection

Symmetry
In this paper, we investigate the algebraic conditions of algebraic Schouten solitons on three-dimensional Lorentzian Lie groups associated with the perturbed canonical connection and the perturbed Kobayashi–Nomizu connection. Furthermore, we provide the

Harmonicity and Minimality of vector fields on four-dimensional Lorentzian lie groups

, 2014
We consider four dimensional lie groups equipped with left invariant Lorentzian Einstein metrics, and determine the harmonicity properties of vector fields on these spaces.

Algebraic ∗‐Ricci solitons of three‐dimensional Lorentzian contact Lie groups

Mathematische Nachrichten
In this paper, we introduce the notion of algebraic *$\ast$ ‐Ricci solitons of three‐dimensional almost contact Lorentzian Lie groups, which represents a fundamentally novel class of solitons.

Maximal group of isometries of the lorentzian lie group A(1)xA(1)

2022
The purpose of this paper is to indicate the metric tensor on the Lie group GIV=A+(1)xA +(1), under which it admits a one-parameter group of motions that leave the identity element of the Lie group fixed, and write out the action of this one-parameter group in the coordinates associated with the matrix representation of this Lie group.
