Isometry Groups of 4-Dimensional Nilpotent Lie Groups

Journal of Mathematical Sciences, 2017
A complete description of the isometry groups of left invariant metrics on 4-dimensional simply connected nilpotent Lie groups \(N\) is given. There are only two nonabelian 4-dimensional nilpotent Lie algebras - 2-nilpotent \(n_3\oplus \mathbf R\) and 3-nilpotent \(n_4\).

The heat kernel of sub-Laplace operator on nilpotent Lie groups of step two

Applicable Analysis, 2021
The Laguerre calculus is widely used for the inversion of differential operators on the Heisenberg group. Applying the Laguerre calculus established on nilpotent Lie groups of step two in Chang et al.

Positive Hermitian curvature flow on complex 2-step nilpotent Lie groups

Manuscripta mathematica, 2020
We study the positive Hermitian curvature flow of left-invariant metrics on complex 2-step nilpotent Lie groups. In this setting we completely characterize the long-time behaviour of the flow, showing that normalized solutions to the flow subconverge to ...

Killing–Yano 2-forms on 2-step nilpotent Lie groups

Geometriae Dedicata, 2019
In this article we show that the only 2-step nilpotent Lie groups which carry a non-degenerate left invariant Killing–Yano 2-form are the complex Lie groups.
