论文摘要
记住彼得·弗林德（Peter Freund）对超级重力的基本贡献，尤其是对于尺寸压实问题的问题，通过横向至较低维理论的非紧密空间来考虑减少。通过在单个可正常的零元素横向波函数与横向状态连续体的边缘之间发生质量间隙，避免了Kaluza-Klein状态连续体的已知问题。这种还原风格不会对较低维理论产生正式一致的截断，因此开发较低的有效理论需要将位于质量差距上方的Kaluza-Klein状态整合在一起。
Remembering the foundational contributions of Peter Freund to supergravity, and especially to the problems of dimensional compactification, reduction is considered with a non-compact space transverse to the lower dimensional theory. The known problem of a continuum of Kaluza-Klein states is avoided here by the occurrence of a mass gap between a single normalizable zero-eigenvalue transverse wavefunction and the edge of the transverse state continuum. This style of reduction does not yield a formally consistent truncation to the lower dimensional theory, so developing the lower-dimensional effective theory requires integrating out the Kaluza-Klein states lying above the mass gap.
