AI 中文摘要
我们证明,在庞加莱$\mathrm{AdS}_D$中,Carroll-Weyl规范零弦的径向扇区在BRST上同调中是局部平凡的。在商适应的BFV基中,径向坐标、其共轭动量以及相关的鬼场构成一个可收缩的四重态。一个显式的收缩同伦将此约化扩展到局部空间射流的完整代数,恰好留下$(D-1)$维ILST BRST复形。同一四重态携带零净Virasoro中心荷,因此母理论的反常条件$D=27$下降为ILST条件$d=26$。
英文摘要
We show that the radial sector of a Carroll-Weyl gauged null string in Poincaré $\mathrm{AdS}_D$ is locally trivial in BRST cohomology. In a quotient-adapted BFV basis, the radial coordinate, its conjugate momentum, and the associated ghosts form a contractible quartet. An explicit contracting homotopy extends this reduction to the full algebra of local spatial jets, leaving precisely the $(D-1)$-dimensional ILST BRST complex. The same quartet carries zero net Virasoro central charge, so that the anomaly condition of the parent theory, $D=27$, descends to the ILST condition $d=26$.
