In this work, we propose a model of noncommutative cosmology through the deformation of minisuperspace. We focus on an exponentially potential with a homogeneous scalar field minimally coupled to gravity in the spatially flat universe. To process, we use a particular case of noncommutativity by making a deformation of space coordinates only. Then, we compare results in both the commutative model and the noncommutative one.

变形空间-空间参数对具有指数势的规范标量场模型的影响。空间平坦的弗里德曼-勒梅特-罗伯逊-沃克 (FLRW) 宇宙的情况

在这项工作中,我们通过微型超空间的变形提出了一个非交换宇宙学模型。我们专注于在空间平坦的宇宙中具有与重力最小耦合的均匀标量场的指数势。为了处理,我们通过仅对空间坐标进行变形来使用非交换性的特殊情况。然后,我们比较了交换模型和非交换模型的结果。
