A generalization of the concept of a manifold, on which the functions take values in a commutative superalgebra. The structure of a super-manifold on a differentiable manifold with structure sheaf is defined by a sheaf of commutative superalgebras over the sheaf , whereby any point possesses a neighbourhood such that the ringed space is isomorphic to , where is the exterior algebra with odd generators. Analytic super-manifolds are defined in the same way. The differentiable (or analytic) super-manifolds form a category whose morphisms are the morphisms of ringed spaces that are even on the structure sheaves. The pair () is called the dimension of the super-manifold. A super-manifold of the form , where is an open submanifold in , is called a super-domain of dimension . Every super-manifold is locally isomorphic to a super-domain.

If is a vector bundle over , then the sheaf of sections of the bundle defines the structure of a super-manifold on . Every differentiable super-manifold is isomorphic to a super-manifold of the form ; in the complex analytic case this is not true. At the same time there are more morphisms in the category of super-manifolds than in the category of vector bundles.

A super-manifold can be defined by a functor from the category of commutative superalgebras into the category of sets; this functor assigns to the superalgebra the set , where is the set of prime ideals in , endowed with the natural sheaf of superalgebras (see Representable functor).

The basic concepts of analysis on differentiable manifolds are also applied to super-manifolds.

The concept of a super-manifold also arose in theoretical physics; it enables one to join particles with Bose–Einstein statistics and Fermi–Dirac statistics into single multiplets, and also enables one to join the internal and dynamic symmetries of gauge theories in a single super-group.

As noted above, part of the motivation for the study of super-manifolds comes from theoretical physics, in particular supersymmetry and supergravity, [a4]. Not all authors agree that the definitions given above are the best for these purposes, cf. [a2], [a3]. "Desirability axioms" for a "well-behaved" category of super-manifolds are discussed in [a1]. Some definitions of super-manifolds satisfy these axioms, for instance the one above, and some others do not.
