Closure (computer science): A feature in some computer programming languages that allows a procedure to bind to its environment, so that it may be called (and its internal variables utilized) from anywhere within the process, instead of using C-like scope rules to limit its availability. [e]- Closure (topology): A set together with all its limit points. [e]
Closure operator: An idempotent unary operator on subsets of a given set, mapping a set to a larger set with a particular property. [e]
- Algebraic closure: A field extension generated by the roots of all polynomials over the ground field. [e]
- Integral closure: The ring of elements of an extension of a ring which satisfy a monic polynomial over the base ring. [e]
