How to define horizontal and vertical curly braces ? Answer is here !!!


Vertical curly braces

To define a left vertical curly brace we use the attribute

\left\{ 

to close it we use

\right\}

To do not close ou do not open one of it, we use the dot attribute .
For example:

$$
\sigma(s,i) = \left\{
   \begin{array}{ll}
       \tau_{si} & \mbox{si } \{s,i\} \in E \\
       \infty & \mbox{sinon.}
   \end{array}
\right.
$$

$$ \sigma(s,i) = \left\{ \begin{array}{ll} \tau_{si} & \mbox{si } \{s,i\} \in E \\ \infty & \mbox{sinon.} \end{array} \right. $$

$$
\left.
   \begin{array}{ll}
       \tau_{si} & \mbox{si } \{s,i\} \in E \\
       \infty & \mbox{sinon.}
   \end{array}
\right \}=\sigma(s,i)
$$

$$ \left. \begin{array}{ll} \tau_{si} & \mbox{si } \{s,i\} \in E \\ \infty & \mbox{sinon.} \end{array} \right \}=\sigma(s,i) $$

Horizontal curly braces

For horizontal curly braces, we use the fonctions

\underbrace{...}
\overbrace{...}
$$
\underbrace{\ln \left( \frac{5}{6} \right)}_{\simeq -0.1823}
< \overbrace{\exp \left(\frac{1}{2} \right)}^{\simeq 1.6487}
$$

$$ \underbrace{\ln \left( \frac{5}{6} \right)}_{\simeq -0.1823} < \overbrace{\exp \left(\frac{1}{2} \right)}^{\simeq 1.6487} $$
