It would help me to have a decently long list of mathematical theorems (undergraduate mathematics) proved with TLA+ I can look at. And how to run them and interpret them.

There is a basic tutorial available on the INRIA website: https://tla.msr-inria.inria.fr/tlaps/content/Documentation/Tutorial/The_example.html Really though the best way to learn is to just try to prove a very simple statement and see how it goes, reading other peoples' proofs for inspiration. Here are my attempts at some basic proofs: https://github.com/tlaplus/Examples/tree/master/specifications/LearnProofs You can also look at the tlaplus/examples repo in general, there is a table in the README with checkboxes marking every spec that includes proofs: https://github.com/tlaplus/Examples The TLA+ proof language is usually applied to prove statements that are shallow but broad, as in very simple mathematical statements but a lot of them. This is what you have to do to prove an algorithm correct. Each individual step in the algorithm is usually mathematically simple, but there are a lot of them. I am not aware of the TLA+ proof language being used to prove "deep" mathematical theorems like you hear coming out of the Rocq and Lean community, but perhaps examples exist.

The problem I struggle with is that the TLA+ book does not cover the verification of mathematical proofs. purely mathematical. Have scrutinised Stephan's links to actual proofs of Cantor's theorem. But can one use the software to show that they are indeed correct. This is the field of verification that I have interest in at this moment. Can one find a tutorial about how specific mathematical proofs can be defined and verified ? Thank you so very much Marta
