nLab super Poincaré group

Idea

The super Poincaré group is the Lie integration in supergeometry of the super Poincaré Lie algebra. This is a super Lie group-extension of the ordinary Poincaré group.

In physics an action/symmetry of the super Poincaré group is also called a supersymmetry.

The coset (super Klein geometry) of a super Poincaré group by the Spin group/Pin group inside it is a super translation group, whose underlying supermanifold is a super Minkowski spacetime.
