BTZ是否是CTMG的单独超选扇区?

Is BTZ a separate superselection sector of CTMG?

S. Deser, J. Franklin

摘要:

我们表现出精确的解决方案(正)物质耦合到宇宙TMG,他们必然会演变成锥形奇点/负质量,而不是物理黑洞,BTZ。通过提供证据表明后者构成了一个独立的,“超选择”,从物理上无法到达的部门,他们也提供了保留TMG的原始“错误”G符号的理由,以确保激励稳定性。

英文摘要:

We exhibit exact solutions of (positive) matter coupled to cosmological TMG; they necessarily evolve to conical singularity/negative mass, rather than physical black hole, BTZ. By providing evidence that the latter constitutes a separate, "superselection", sector not reachable from the physical one, they also provide justification for retaining TMG's original "wrong" G-sign to ensure excitation stability here as well.
