- Pointed_set abstract "In mathematics, a pointed set is a set with a distinguished element , which is called the basepoint. Maps of pointed sets (based maps) are those functions that map one basepoint to another, i.e. a map such that . This is usually denoted.Pointed sets may be regarded as a rather simple algebraic structure. In the sense of universal algebra, they are structures with a single nullary operation which picks out the basepoint.The class of all pointed sets together with the class of all based maps form a category.A pointed set may be seen as a pointed space under the discrete topology or as a vector space over the field with one element.There is a faithful functor from usual sets to pointed sets, but it is not full, and these categories are not equivalent.".
