I have a several condition for a mathematical results to be valid but I don't know how to put them in several lines with big braces after and then write some text.

$\beta_{1}>\epsilon_{1}$ \\
$ E_{2} <0$ \leftarrow the equilibrium point EP3 is stable

I coudn't find any think about this neither here or other places after some research.

  • I just forgot it here .

  • it is best if you always provide a complete small document that shows the problem, not just a fragment (then you would for example also notice that you have \rightarrow outside math mode which will generate an error. It is helpful if code fragments don't have errors unrelated to the question. Jan 24, 2020 at 17:29
  • Thanks I will do that next time. I wrote the code just to clarify my question.

If I understand you correctly, something like

enter image description here




\beta_{1} &> \epsilon_{1}\\
\mu_{0}   &<0\\
E_{2}     &<0
\right\} \leftarrow \text{the equilibrium point $EP3$ is stable}

  • yes,exactly thanks

The mathtools package defines a rcases environment:

\usepackage{mathtools} % loads amsmath
\[ \begin{rcases}
\beta_{1}> epsilon_{1}  \\
 \mu_{0}<0 \\
 E_{2} <0
\leftarrow \text{the equilibrium point EP3 is stable}

or with empheq (which loads mathtools):

\begin{empheq}[right={\empheqrbrace \leftarrow \text{the equilibrium point EP3 is stable}]{align*}    
    \beta_{1}&> epsilon_{1}  \\
     \mu_{0} &< 0 \\
     E_{2} &< 0
