论文摘要

在二维字符串理论中,由于其度量耦合与DILATON耦合之间的取消,探针D0-Brane没有看到黑洞的奇异性。通过考虑合适的包裹膜,可以在大型$ d $尺寸的Schwarzschild黑洞中使用类似的机制。从渐近观察者那里,包裹的膜看起来一无所有,而奇异性之外的时间段轨迹的延续表明,它会像瞬间伸展的瞬时空间一样出现。无效的轨迹可以扩展到超出奇异性的无效轨迹。不仅有效的粒子,而且包裹膜上的有效串也可以表现出相同的特征。

In two-dimensional string theory, a probe D0-brane does not see the black hole singularity due to a cancellation between its metric coupling and the dilaton coupling. A similar mechanism may work in the Schwarzschild black hole in large $D$ dimensions by considering a suitable wrapped membrane. From the asymptotic observer, the wrapped membrane looks disappearing into nothing while the continuation of the time-like trajectory beyond the singularity suggests that it would reappear as an instantaneous space-like string stretching from the singularity. A null trajectory can be extended to a null trajectory beyond the singularity. Not only the effective particle but an effective string from the wrapped membrane can exhibit the same feature.
