论文摘要
在弱重力猜想的背景下，黑洞和麸皮的准肠道概念被定义为具有消失的地平线大小或表面重力的特性。得出的是，这种对象遵守无力的条件。在此简短的说明中，我提出了一种简化的推导，该推导基本上存在于Breitenlohner，Gibbons和Maison率先进行的定时降低的形式中。这种形式主义还提供了用于引力（和虫洞）的准肠道的自然定义，它通过轴突通量来源，并加强了这样一个论点，即宏观轴孔孔不会在路径积分中贡献，因为它们在欧几里得的意义上是自我抑制的。
In the context of the Weak Gravity Conjecture the notion of quasi-extremality for black holes and branes was recently defined as the property of having either vanishing horizon size or surface gravity. It was derived that such objects obey a no-force condition. In this short note I present a simplified derivation that is essentially present in the formalism of timelike reduction pioneered by Breitenlohner, Gibbons and Maison. This formalism also provides the natural definition of quasi-extremality for gravitational instantons (and wormholes) sourced by axion fluxes and strengthens the argument that macroscopic axion wormholes do not contribute in the path integral since they are self-repulsive in a Euclidean sense.
