A simple, closed-form solution to the Yang-Mills field equations is presented which has a non-Abelian firewall — a spherical “horizon” where the energy density diverges. By the gravity/gauge duality, this non-Abelian firewall implies the existence of a gravitational firewall. Gravitational firewalls have been proposed as a way of resolving the information loss paradox, but at the cost of violating the equivalence principle.

非阿贝尔防火墙

提出了一个简单的、封闭形式的杨-米尔斯场方程解，它有一个非阿贝尔防火墙——一个能量密度发散的球面“视界”。通过重力/规范二元性，这个非阿贝尔防火墙暗示了引力防火墙的存在。引力防火墙已被提出作为解决信息丢失悖论的一种方法，但其代价是违反了等效原则。
