论文摘要
我们表明，由KAC-MOODY代数A1 +++具有其向量表示的Kac-Moody代数A1 +++的非线性实现构成的重力理论不允许宇宙常数。该理论中宇宙常数的存在与重力二元对称性的破坏有关。
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.
