Twist of Lie algebras by 6 dimensional subalgebra
arXiv:math/0008055 · doi:10.1016/S0034-4877(01)80059-8
Abstract
A new non-standard deformation of all types of classical Lie algebras is constructed by means of Drinfel'd twist based on a six dimensional subalgebra. This is an extension of extended twists introduced by Kulish et al. For the algebra M_3 = so(3,2), a relation to a known non-standard deformation is discussed.
