👉 In mathematics, a poliad is an extension of the notion of a ring or field to include additional structure. It can be defined as a collection of objects that are themselves objects in some way (e.g., sets, groups, rings) and which have operations that behave like those in these structures.
Poliads are particularly useful in algebraic geometry, where they allow for the study of varieties with extra structure. For instance, in algebraic geometry, poliad objects can be used to construct
