卡茨-穆迪代数与宇宙学常数

Kac-Moody algebras and the cosmological constant

Peter West

摘要:

我们表明,从非线性实现的半直积的卡茨-穆迪代数A1+与其向量表示的引力理论不允许一个宇宙学常数。该理论中宇宙学常数的存在与引力对偶对称性破缺有关。

英文摘要:

We show that the theory of gravity constructed from the non-linear realisation of the semi-direct product of the Kac-Moody algebra A1+++ with its vector representation does not allow a cosmological constant. The existence of a cosmological constant in this theory is related to the breaking of the gravitational duality symmetry.
