我们提出了三维平坦空间中的非平凡高自旋理论的第一个例子。我们提出了平面空间边界条件,并证明了它们的一致性,这个理论。我们发现,渐近对称代数是一个(中心扩展)更高的自旋推广的Bondi-Metzner-Sachs代数,我们详细描述。我们还解决了更高的自旋类似物的平坦空间宇宙学的解决方案和可能的推广。
We present the first example of a nontrivial higher spin theory in three-dimensional flat space. We propose flat-space boundary conditions and prove their consistency for this theory. We find that the asymptotic symmetry algebra is a (centrally extended) higher spin generalization of the Bondi-Metzner-Sachs algebra, which we describe in detail. We also address higher spin analogues of flat space cosmology solutions and possible generalizations.
