本文从代数的角度研究例外几何中具有U-对偶群En(n)的广义超同态。通过将李代数en$ {\mathfrak{e}}_n $$推广到无限维Borcherds超代数,并推广到en+1$$ {\mathfrak{e}}_{n+1} $$,广义李导数可以用一种简单的方式表示,并且对于任意n ≤ 7,表达式具有相同的形式。变换的封闭性由Jacobi恒等式和en+1$$ {\mathfrak{e}}_{n+1} $$关于en$ {\mathfrak{e}}_n $$的分次得出。
A bstractWe study generalized diffeomorphisms in exceptional geometry with U-duality group En(n) from an algebraic point of view. By extending the Lie algebra en$$ {\mathfrak{e}}_n $$ to an infinite-dimensional Borcherds superalgebra, involving also the extension to en+1$$ {\mathfrak{e}}_{n+1} $$, the generalized Lie derivatives can be expressed in a simple way, and the expressions take the same form for any n ≤ 7. The closure of the transformations then follows from the Jacobi identity and the grading of en+1$$ {\mathfrak{e}}_{n+1} $$ with respect to en$$ {\mathfrak{e}}_n $$.
