幂零流形上涌现引力的T-对偶性

T-duality of emergent gravities on nilmanifolds

Raju Roychowdhury, Leonardo Soriani

AI总结:

该研究从李代数角度探究拓扑T-对偶幂零流形间广义度规的传递,给出涌现引力的辛B场性质在传递中保留的必要条件,提供低维自T-对偶零H-通量流形的实例,并分析非零H-通量下的失效原因。

摘要:

我们从李代数的角度研究拓扑T-对偶幂零流形之间广义度规的传递。涌现引力是带有辛B场的广义度规,但上述传递过程可能无法保留这一附加性质。我们给出了该性质得以保留的必要条件,并在4维和6维、H-通量为零的自T-对偶幂零流形上提供了有效实例。我们还讨论了在H-通量非零的情况下这一过程为何失效。

英文摘要:

We study the transport of generalized metrics between topological T-dual nilmanifolds through a Lie algebraic point of view. Emergent gravities are generalized metrics with symplectic B-fields. But this additional property might not be preserved by the aforementioned transport. We describe a necessary condition for it to happen and provide working examples on self-T-dual nilmanifolds with zero $H$-flux in both 4 and 6 dimensions. We also discuss how this procedure fails in the presence of a non-zero $H$-flux.
