非交换谱几何的线性稳定性

Linear stability of noncommutative spectral geometry

Mairi Sakellariadou, Apimook Watcharangkool

摘要:

我们考虑的范围内的一个4维流形扭转的光谱行动,并表明,在真空的情况下,运动方程减少到爱因斯坦方程,确保理论的线性稳定性。随后调查的非真空的情况下,我们认为几乎可交换的扭转几何的谱作用,并表明,哈密顿量是有界的从下面,一个结果,保证了线性稳定的理论。

英文摘要:

We consider the spectral action within the context of a 4-dimensional manifold with torsion and show that, in the vacuum case, the equations of motion reduce to Einstein's equations, securing the linear stability of the theory. To subsequently investigate the nonvacuum case, we consider the spectral action of an almost commutative torsion geometry and show that the Hamiltonian is bounded from below, a result which guarantees the linear stability of the theory.
