48 results for super-Lie groups

A super Lie group is a group whose operations are GG^{\infty} mappings in the sense of Rogers. Thus the underlying supermanifold possesses an atlas whose transition functions are GG^{\infty} functions. Moreover the images of our charts are open subsets of a graded infinite-dimensional Banach space since our space of …

We derive the canonical forms of super Riemannian metrics and the local isometry groups of such metrics. For certain super metrics we also compute the simply connected covering groups of the local isometry groups and interpret these as local spin groups of the super metric. Using a generalization of a Theorem of Rogers…

A homogeneous space is a manifold on which a Lie group acts transitively. Super generalization of this concept is also studied in [2] and [4]. In this paper we explicitly show that super Lie group GL(m|n) acts transitively on supergrassmannian G_{k|l}(m|n). In this regard, by using functor of point approach, this actio…

With the usual definition of a super Hilbert space and a super unitary representation, it is easy to show that there are lots of super Lie groups for which the left-regular representation is not super unitary. I will argue that weakening the definition of a super Hilbert space (by allowing the super scalar product to b…

A new generalization of Grassmannians in supergeometry, called νν-Grassmannians, are constructed by gluing νν-domains. By a νν-domain, we mean a superdomain with an odd involution say νν on its structure sheaf, as morphism of modules. Then we show that νν-Grassmannians are homogeneous superspaces. In addition, in …
