通用几何形状、十一维和E11

Generalised geometry, eleven dimensions and E11

Peter West

摘要:

我们构建了E11的非线性实现及其在低水平的11维中的第一个基本表示。这些场依赖于通常的时空坐标以及二形和五形坐标。我们推导出包含三种形式和六种形式场的动力学项,并表明当我们限制它们的场依赖性仅在通常的时空上时,我们恢复了正确的自对偶关系。如果这一结果推广到引力场,那么非线性实现是最大超引力理论的扩展,如前所述。我们还评论之间的连接不同的方法来广义几何。

英文摘要:

We construct the non-linear realisation of E11 and its first fundamental representation in eleven dimensions at low levels. The fields depend on the usual coordinates of space-time as well as two form and five form coordinates. We derive the terms in the dynamics that contain the three form and six form fields and show that when we restricted their field dependence to be only on the usual space-time we recover the correct self-duality relation. Should this result generalise to the gravity fields then the non-linear realisation is an extension of the maximal supergravity theory, as previously conjectured. We also comment on the connections between the different approaches to generalised geometry.
