Gregory and Laflamme showed that certain nonextremal black strings (and p-branes) are unstable to linearized perturbations. It is widely believed that this instability will cause the black string horizon to classically pinch off and then quantum mechanically separate, resulting in higher dimensional black holes. We argue that this cannot happen. Under very mild assumptions, classical event horizons cannot pinch off. Instead, they settle down to new static black string solutions which are not translationally invariant along the string.
格雷戈里和拉弗拉姆指出，某些非极端的黑弦（以及p膜）对于线性微扰是不稳定的。人们普遍认为，这种不稳定性将导致黑弦视界在经典意义上收缩并随后在量子力学意义上分离，从而产生高维黑洞。我们认为这种情况不会发生。在非常温和的假设下，经典事件视界不会收缩。相反，它们会稳定到新的静态黑弦解，这些解沿弦方向不是平移不变的。
