论文摘要
通过公制函数的扩展，已经研究了近野型区域中的混乱。在本文中，我们调查了近摩恩区域中的混乱，并在距带电的Kiselev黑洞的一定距离处。 Lyapunov指数的值由Jacobian矩阵准确计算。黑洞周围充满电的粒子的角动量不仅会影响指数，而且会影响平衡轨道的位置。随着角动量的增加，该位置逐渐远离地平线。我们发现，界限在距地平线的一定距离处违反，并且当粒子的电荷质量比固定时，近摩恩区域没有违规。标准化因子的小价值更可能导致违规行为。
The chaos bound in the near-horizon regions has been studied through the expansions of the metric functions on the horizon. In this paper, we investigate the chaos bound in the the near-horizon region and at a certain distance from the horizon of a charged Kiselev black hole. The value of the Lyapunov exponent is accurately calculated by a Jacobian matrix. The angular momentum of a charged particle around the black hole affects not only the exponent, but also the position of the equilibrium orbit. This position gradually moves away from the horizon with the increase of the angular momentum. We find that the the bound is violated at a certain distance from the horizon and there is no violation in the near-horizon region when the charge mass ratio of the particle is fixed. The small value of the normalization factor is more likely to cause the violation.
