The endpoint adjoining the square bracket is known as closed, while the endpoint adjoining the parenthesis is known as open. If both types of brackets are the same, the entire interval may be referred to as closed or open as appropriate. Whenever infinity or negative infinity is used as an endpoint (in the case of intervals on the real number ...
The empty set and are the only intervals that are both open and closed. A half-open interval has two endpoints and includes only one of them. It is said left-open or right-open depending on whether the excluded endpoint is on the left or on the right. These intervals are denoted by mixing notations for open and closed intervals. [3]
[45] [46] The endpoint adjoining the square bracket is known as closed, whereas the endpoint adjoining the parenthesis is known as open. [44] In group theory and ring theory, brackets denote the commutator. In group theory, the commutator [g, h] is commonly defined as g −1 h −1 g h .
The open-closed template wraps its argument in a left round bracket, right square bracket. These are used to delimit an open-closed interval in mathematics, that is one which doesn't include the start point but does include the end point. The template uses {} to ensure there is no line break in the expression and the Greek characters look better.
The closed-closed template wraps its argument in a left square bracket, right square bracket. These are used to delimit a closed-closed interval in mathematics, that is one which includes both the start and end points. The template uses {} to ensure there is no line break in the expression and format Greek characters better.
If you’re considering investing in a mutual fund or ETF, you might have heard the terms “open-end” and “closed-end” -- and immediately scratched your head in confusion. Indeed, these are ...

Brackets are commonly found in major North American professional sports leagues and in U.S. college sports. Often, at the end of the regular season, the league holds a post-season tournament (most commonly called a playoff) to determine which team is the best out of all of the teams in the league.
