# Hooks for many hypotheses or conclusions

Good morning!

How can I do this?

Thank's a lot!!!

EDIT

The below answer has this problem:

\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{displaymath}
\text{If}\Rightarrow
\begin{cases}
\text{Conclusion }1, & a=1\\
\text{Conclusion }2, & a=2\\
\text{Conclusion }3, & a=3
\end{cases}
\end{displaymath}
\begin{displaymath}
\left.
\begin{array}{@{}r@{}}
\text{If }1\\
\text{If }2\\
\text{Longif }3
\end{array}
\right\}
\Rightarrow\text{Conclusion}
\end{displaymath}
\end{document}


EDIT

To have the cases in an itemize as described in the question edit, use $...$ instead of displayed equation. However, I am not sure it is a good idea to have this type of case brackets in an itemization, it looks a bit strange.

\begin{itemize}
\item If $\Rightarrow$ Conclusion
\item $\left. \begin{array}{@{}r@{}} \text{If }1\\ \text{If }2\\ \text{Longif }3 \end{array} \right\} \Rightarrow\text{Conclusion}$
\end{itemize}


• This seems very good, but I have problem with itemize. Jun 4 '18 at 7:33
• @ΚώσταςΚούδας You can use a minipage in before the brace. See edit. Jun 4 '18 at 7:50
• I 'm sorry... I didn't explain it well. I have problem when it is part of itemizing, as you can see at my edited answer. Jun 4 '18 at 8:34
• @ΚώσταςΚούδας I have changed the edit. Jun 4 '18 at 10:42
• Thank's a lot! You are right about the strange looking of cases in itemization. I 'm thinking about it! Thank's!!! Jun 6 '18 at 5:44
