论文摘要
在本文中，我们提出了新型的非权威性超级别，这对应于扩大的延长Bargmann代数的超对称扩展。构建了上述超级统治下的三维非相关性Chern-Simons超重力动作。新的非忠实超级级别的超级代理允许在非权利主义超级重力理论中适应宇宙常数。有趣的是，我们表明，此处介绍的非权威主义超级性理论之一导致最近引入的麦克斯韦外来式巴格曼超级重力，当考虑到平坦的限制$ \ ell \ elly \ rightarrow \ rightarrow \ infty $。此外，我们表明，这两个描述都可以用Nappi-witten代数或扩展的Newton-Hooke Superalgebra的超对称扩展来编写。
In this paper, we present novel non-relativistic superalgebras which correspond to supersymmetric extensions of the enlarged extended Bargmann algebra. The three-dimensional non-relativistic Chern-Simons supergravity actions invariant under the aforementioned superalgebras are constructed. The new non-relativistic superalgebras allow to accommodate a cosmological constant in a non-relativistic supergravity theory. Interestingly, we show that one of the non-relativistic supergravity theories presented here leads to the recently introduced Maxwellian exotic Bargmann supergravity when the flat limit $\ell \rightarrow\infty$ is considered. Besides, we show that both descriptions can be written in terms of a supersymmetric extension of the Nappi-Witten algebra or the extended Newton-Hooke superalgebra.
