So, first off, I am completely new to LaTex and actually opened my first document today. I use texlive, and the amsmath package is also used here.
I want to write down my proof that the continuum hypothesis is equivalent to a certain proposition. My proof consists of two implications, that I would like to specify before I start proving them. So now I'm trying to make a nice implication that I can refer to later (I was thinking equation-environment), that is centered. Since the implication is between two propositions, it just contains text and a \Longrightarrow. It is too long to fit in the page, so I wanted to break it, placing the first statement on top, the arrow in the middle and the second statement at the bottom. I having bene looking on the internet for hours, and {split} worked, except that now everything is aligned at the right of the page, which isn't my intention. It should be centered. Can anybody help me out? {multline},{align*},{align},{eqnarray},...all weren't recognised by LaTeX.
This is my code for the "equation":
\begin{equation}
\begin{split}
\label{implication}
{\displaystyle \textit{De continu\"umhypothese}}\\
\Longrightarrow \\
{\textit{Als $X$ een overaftelbare deelverzameling is van $\mathbb{R}$,}}
{\textit{ dan is er een bijectie van $X$ naar $\mathbb{R}$.}}
\end{split}
\end{equation}
Thank you very much!
