普朗克质量和伸缩子场作为非对易参数的函数

Planck mass and Dilaton field as a function of the noncommutative parameter

S. Zaim, Z. Aouachria

摘要:

在非对易规范引力中得到了变形的Bianchi I型度规。在非对易性参数中,确定了规范势(四分体场)和标量曲率的二阶。导出了Einstein-Hilbert作用量的非对易修正。我们得到了非对易时空的普朗克质量作为非对易参数θ的函数,这意味着非对易性改变了时空的结构和拓扑。

英文摘要:

A deformed Bianchi type I metric in noncommutative gauge gravity is obtained. The gauge potential (tetrad fields) and scalar curvature are determined up to the second order in the noncommutativity parameters. The noncommutativity correction to the Einstein-Hilbert action is deduced. We obtain the Planck mass, on noncommutative space-time as a function of the noncommutative parameter θ, which implies that noncommutativity has modified the structure and topology of the space-time.
