Diameter of Commuting Graphs of Lie Algebras
Hieu V. Ha, Hoa D. Quang, Vu A. Le +1
In this paper, we study the connectedness of the commuting graph of a general Lie algebra and provide a process to determine whether the commuting graph is connected or not, as wel…

Classification of Solvable Lie algebras whose non-trivial Coadjoint Orbits of simply connected Lie groups are all of Codimension 2
Hieu Van Ha, Vu Anh Le, Tu Thi Cam Nguyen +1
We give a classification of real solvable Lie algebras whose non-trivial coadjoint orbits of corresponding simply connected Lie groups are all of codimension 2. These Lie algebras…

Classification of a Class of Solvable Real Lie Algebras by using Techniques in Matrix Theory
Hieu Ha Van, Vu Le Anh, Hoa Duong Quang
We give a complete classification of the class of Lie algebras of simply connected real Lie groups whose nontrivial coadjoint orbits are of codimension 1. Such a Lie group belongs…
