Vierbein形式中的多重引力子理论
Multi-graviton theory in vierbein formalism
摘要:
最近,人们考虑了与Kaluza-Klein(KK)理论的$S^1$紧化相对应的简单闭合电路图上的多引力子理论。本文将这一理论推广到一般图上,并研究了一般图上的粒子模式。此外,我们推广它在一个可能的非线性理论的基础上的vierbein形式主义和研究宇宙学的解决方案。
英文摘要:
Recently, multi-graviton theory on a simple closed circuit graph corresponding to the $S^1$ compactification of the Kaluza-Klein (KK) theory has been considered. In the present paper, we extend this theory to that on a general graph and study what modes of particles are included. Furthermore, we generalize it in a possible non-linear theory based on the vierbein formalism and study cosmological solutions.
