没有奇点的宇宙De Sitter宇宙学的群方法

Universe Without Singularities. A Group Approach to De Sitter Cosmology

Ignazio Licata

摘要:

在过去的几年里,传统的大爆炸场景已经被宇宙演化的量子特征的研究所深刻地修改,再次提出了在宇宙尺度上使用局部物理定律的问题,特别是关于宇宙学常数的作用。群扩张方法表明,De Sitter群是Poincare群的唯一推广,形式上证明了宇宙学常数的使用,并对量子宇宙学中的Hartle-Hawking边界条件提出了新的解释.

英文摘要:

In the last years the traditional scenario of Big Bang has been deeply modified by the study of the quantum features of the Universe evolution, proposing again the problem of using local physical laws on cosmic scale, with particular regard to the cosmological constant role. The group extention method shows that the De Sitter group univocally generalizes the Poincare group, formally justifies the cosmological constant use and suggests a new interpretation for Hartle-Hawking boundary conditions in Quantum Cosmology.
