具有特殊G2-structures的李代数的构造

Construction of Lie algebras with special G2-structures

Victor Manero

摘要:

给出了从具有辛半At SU(3)-结构和半At SU(3)-结构的6维李代数出发,得到具有闭和上闭G2-结构的7维李代数的方法.最后,我们描述了所有由具有SU(3)-辛半结构的6维可解李代数得到的具有闭G2-结构的7维李代数.

英文摘要:

We give a method to obtain new 7-dimensional Lie algebras endowed with closed and coclosed G2-structures starting from 6-dimensional Lie algebras with symplectic half- at SU(3)-structures and half- at SU(3)- structures, respectively. Finally, we describe all the 7-dimensional Lie algebras with a closed G2-structure that are obtained with this method from the 6-dimensional solvable Lie algebras admitting a symplectic half- at SU(3)- structure.
