\lBrace \rBrace

The commands \lBrace and \rBrace are used in LaTeX to create left and right curly braces, respectively, which are often used as delimiters in mathematical expressions. These braces are typically used to group expressions or to denote sets, intervals, or piecewise functions.

Examples

f (x) = {[x^{2} - x if x \geq 0 if x < 0]}

Piecewise function definition using curly braces as delimiters.

f(x) = \lBrace \begin{array}{ll} x^2 & \text{if } x \geq 0 \\ -x & \text{if } x < 0 \end{array} \rBrace

S = {[x \in R ∣ x^{2} < 4]}

Set notation using curly braces to define a set of real numbers.

S = \lBrace x \in \mathbb{R} \mid x^2 < 4 \rBrace

{[a, b, c]}

Simple set notation using curly braces to list elements.

\lBrace a, b, c \rBrace
