The interesting thing was most of my searches kept giving me pre-2002 results. Two others that might have been more recent had broken links. I found one more for next week but it’s an algorithm rather than methodology. Makes me wonder if there’s actually little to no formal verification going on for Erlang programs. Given its use case and popularity, that would be pretty shocking. I’m going to do a more thorough search in next few days.
Disclaimer: I don’t know anything about this at all. My (very rudimentary) understanding of the situation was that more in-depth application of formal methods to Erlang was waiting on the development of session types, which have been yielding fruit for a few years, but perhaps Erlang is a slightly less popular target for this analysis now. I haven’t read the thesis you’ve linked to see how they treat abstract interpretation of message passing; session types might be irrelevant for this.
I would love for someone actually familiar with the development of these things to comment and set the record straight. (In fact, perhaps I’m just commenting in this case so I can draw out someone better informed having a “someone is wrong on the Internet” reaction.)
