论文摘要
提出了与仪表理论和重力中的软玻色子发射相关的通用因子，该因子在轻度仪表中提出。使用这些因素构建了用于从低点构建更高点幅度的逆柔软方法。然后在（轻度）超空间中检查这些想法，并应用于n = 4个Super Yang-Mills和N = 8 Supergravity Theories。一个亮点是在n = 8超级重力中四分之一相互作用顶点的紧凑结果，这是有限分析的关键成分。
Universal factors associated with the emission of a soft boson in gauge theories and gravity, formulated in the light-cone gauge, are presented. The inverse-soft method, for constructing higher-point amplitudes from lower-point ones, using these factors is reviewed. These ideas are then examined in (light-cone) superspace and applied to both the N=4 super Yang-Mills and N=8 supergravity theories. One highlight is a compact result for the quartic interaction vertex in N=8 supergravity, a crucial ingredient for finiteness analyses.
