The Jech–Kunen tree is a specific type of tree used in set theory, particularly in the context of analyzing and demonstrating properties of model theory, forcing, and the structure of certain sets. Named after the mathematicians Thomas Jech and Kenneth Kunen, the tree is often discussed within the framework of large cardinals, set-theoretic forcing, and consistency results in mathematics. A Jech–Kunen tree is defined as an infinite tree that possesses specific properties.
