Nonwellfounded
Nonwellfounded refers to a concept in set theory and logic that describes sets or structures that do not have a well-foundedness property. A well-founded structure is one where there is no infinite descending chain of elements. In simpler terms, if you start at any element and keep going "down" or to a preceding element, you must eventually reach a point where there are no more preceding elements.
Sets that are nonwellfounded violate this principle. This means there can be infinite loops or self-referential
The study of nonwellfounded sets emerged to address paradoxes and limitations found in traditional set theory,
Nonwellfoundedness has implications in various fields, including computer science, where it can be used to model
