\( \newcommand\Ek{\mathbb E_k} \newcommand\Pk{\mathbb P_k} \)

Hello Fellow Comonadists!

Welcome to our shared wiki. As you can see, we can add mathematics! And even define our own commands. Internally it uses MathJax to render formulas. Go to Edit of this page to see how I did it:

Inline mathematics is typeset with $$...$$, \(...\), and math HTML tag. And display style maths with \[...\], \begin{...}...\end{...}.

See for example this $$\Ek A$$ and \(\Pk A\) and also the following:

\[ \Ek A =\ ... \quad\text{and}\quad \Pk A =\ ... \]
