论文摘要
我们研究了在Kerr-Newman-Ads黑洞中具有角运动的带电粒子的Lyapunov指数上的猜想。 Lyapunov指数是根据有效的Lagrangian计算的。我们表明，负宇宙常数降低了粒子的混乱行为，即降低了Lyapunov指数。因此，与平面时空相比，界限在ADS时空中更有效。然而，我们发现当打开黑洞的角动量时，可能会违反界限。此外，我们表明，在一个极端的黑洞中，与非totremal黑洞相比，界限更容易违反。
We investigate the conjectured bound on the Lyapunov exponent for a charged particle with angular motion in the Kerr-Newman-AdS black hole. The Lyapunov exponent is calculated based on the effective Lagrangian. We show that the negative cosmological constant reduces the chaotic behavior of the particle, namely, it decreases the Lyapunov exponent. Hence, the bound is more effective in the AdS spacetime than in the flat spacetime. Nevertheless, we find that the bound can be violated when the angular momenta of the black hole are turned on. Moreover, we show that in an extremal black hole, the bound is more easily violated compared to the nonextremal black hole.
