KeYmaera X provides a simple mechanism for authors of tutorials, demos, and case studies to publish their KeYmaera X model and proof files. This note explains how readers, reviewers, and students can review authior-supplied case studies using the public instance of KeYmaera X.

There are 3 steps:

  • Register an Account
  • Import the case study using the Import Tool
  • Review the case study and associated proof.

Registering an Account

We provide a public instance of KeYmaera X that is easy to use. If you prefer, you may also install KeYmaera X locally by following the instructions on the KeYmaera X website (notice: the Mathematica dependency is non-optional for most case studies. Also, you will need KeYmaera X verion 4.3.8 or newer!).

If you do not want to install KeYmaera X locally – or if your institution does not provide a Mathematica license – you may also create an account on our public instance.

Regardless of whether you use the public instance or a local copy, you will need to create an account. You can do this by entering a username and password in the text fields on the top-right of the screen and clicking the blue “Register” button. Accept the license agreement and select “Industry Mode” from the drop-down box.

KeYmaera X will ask for a URL. This is where you enter the author-supplied URL ending in .json. For example, suppose the author provided the url Then you would enter this URL and press the “Upload” button:

Import model file

If the import is successful, you should be redirected to the “Models” page. This page contains a list of the models that are associated with the user’s case study.

Reviewing Artifacts

To view an imported model, click on its name. A modal dialog should appear.

From this model dialog, you can re-run the author’s proof using the “Prove with Associated Tactic” button at the bottom of the screen. Loading the proof may take a while. If the proof is successful, then you should be re-directed to a page that contains a modal dialog that looks something like this:
