👉 Unenlarged, also known as a "closed" or "unwound" state in mathematics, is a specific type of structure that is not open but has no boundary. In geometry, it refers to a closed figure or plane region that does not contain any holes or gaps. In physics, unenlarged states are often used in quantum mechanics to describe systems where the wave function collapses or becomes undefined, allowing the system to be treated as if it were at rest.
