Welcome to krater!

This is a template for the static website generator Jekyll.

Its purpose is setting up all the plumbing needed by a modern math-intensive website:

• client side rendering of ordinary LaTeX with KaTeX
• server side rendering of arbitrarily complex LaTeX with AnTeX via jekyll-antex
• a nice automatic deploy running on GitHub Actions to host the website on GitHub Pages.

You can get going in no time! All details are in the readme.

The remainder of this page is a demo.

A pretty formula:

$$ F([n]) = \coprod*{i=1}^n F([1]) = \coprod*{i=1}^n X = [n] \otimes X $$

A pretty diagram:

{% tex classes: [antex, display] %} $ \xymatrix{ A\ar[r]^f \ar[d]_f & B \ar[dl]|{\hole\mathrm{id}_B\hole} \ar[d]^g \ C \ar[r]g & D} \qquad \xymatrix{ A\ar[r]^f \ar[d]{g\circ f} & B \ar[dl]|{\hole g\hole} \ar[d]^{h\circ g} \ B \ar[r]_h & C} $ {% endtex %}
