超对称中的 Torsor
Torsors in super-symmetry
AI总结:
本文用 Hopf 代数方法研究仿射超群下的超 torsor,证明适当条件下其均源于普通 torsor,且仿射情形二者一一对应,为超对称 Picard–Vessiot 理论奠定基础。
摘要:
仿射群作用下的 torsor 在超背景中被推广为仿射超群作用下的超 torsor。我们利用 Hopf 代数语言和技术研究这些超 torsor。文中明确证明,在适当假设下,每个超 torsor 都来自一个普通 torsor。特别地,受仿射性限制的对象,即仿射超 torsor 与仿射普通 torsor,被证明恰好一一对应。这些结果在正在构建的超对称 Picard–Vessiot 理论中发挥重要作用。
英文摘要:
Torsors under affine groups are generalized in the super context by super-torsors under affine super-groups. We investigate those super-torsors by using Hopf-algebra language and techniques. It is explicitly shown, under suitable assumptions, that every super-torsor arises from an ordinary torsor. Especially, the objects with affinity restriction, or namely, the affine super-torsors and the affine ordinary torsors are shown to be precisely in one-to-one correspondence. The results play substantial roles in ongoing construction of super-symmetric Picard-Vessiot theory.
