superalgebra and (synthetic ) supergeometry A superpoint is an infinitesimally thickened point whose infinitesimal extension is odd in the sense of supergeometry. A super Cartesian space of vanishing ordinary dimension. A superpoint is a supermanifold of the form . For more see at geometry of physics – superalgebra. The object is also called the odd line. The category of superpoints is the full subcategory of the category of supermanifolds on the superpoints. The algebra of functions on...
