超流形上映射的一个表示公式

A representation formula for maps on supermanifolds

Frédéric Hélein

摘要:

在本文中,我们分析了超函数环的态射的概念,这是将超流形定义为环空间的基本概念(即遵循Berezin,Leites,Manin等)。我们建立了从普通流形上的函数代数到R^{p}的开子集上的函数超代数的所有态射的表示公式|q}。然后,我们得出这个结果的两个后果。第一个是我们可以整合与态射相关的数据,以获得定义在普通空间上的(非唯一)映射(唯一性可以通过限制到方案来实现)。第二个是一个简单而直观的方法,可以通过超空间上定义的映射来计算流形上函数的拉回图像。

英文摘要:

In this paper we analyze the notion of morphisms of rings of superfunctions which is the basic concept underlying the definition of supermanifolds as ringed spaces (i.e. following Berezin, Leites, Manin, etc.). We establish a representation formula for all morphisms from the algebra of functions on an ordinary manifolds to the superalgebra of functions on an open subset of R^{p|q}. We then derive two consequences of this result. The first one is that we can integrate the data associated with a morphism in order to get a (non unique) map defined on an ordinary space (and uniqueness can achieved by restriction to a scheme). The second one is a simple and intuitive recipe to compute pull-back images of a function on a manifold by a map defined on a superspace.
