Closure operators are a fundamental concept in mathematics, particularly in the areas of topology, algebra, and lattice theory. A closure operator is a function that assigns to each subset of a given set a "closure" that captures certain properties of the subset. Closures help to formalize the notion of a set being "closed" under certain operations or properties. \#\#\# Definition Let \\( X \\) be a set.
