变形相空间与$Λ$

On Deformed Phase Space and $Λ$

E. Mena, S. Pérez-Payán, M. Sabido

摘要:

本文研究了具有宇宙学常数的空(4+1)Kaluza-Klein宇宙相空间中的非对易效应。分析了非对易形变对宇宙学常数的影响。最后,我们讨论了该模型中宇宙学常数的起源与四维标度因子与紧致额外维之间的不可交换性有关的可能性。

英文摘要:

In this letter we study the effects of a noncommutative in the phase space of an empty (4+1) Kaluza-Klein universe with cosmological constant. We analyze the effects of the noncommutative deformations on the cosmological constant. Finally we comment on the possibility that the origin of the cosmological constant in this model, is related to the noncommutativity between the 4 dimensional scale factor and the compact extra dimension.
