The (i)Po(m)set Project is a research project at the crossroads of concurrency theory, automata theory, algebra, and geometry. You are at the page of its online seminar.


The seminar takes place on zoom. If you want to participate, send an email to uli@lrde.epita.fr so that we can add you to our mailing list. You will receive about one email per week in average: seminar announcements, reminders, and the zoom link.

Talks generally last at most one hour, including time for questions.

Matt Earnshaw, TUT, Tallinn, Estonia: Monoidal languages
Monoidal language theory is an approach to languages of graphs via the graphical calculus of string diagrams for monoidal categories. The class of regular monoidal languages includes regular languages of words and trees, but also recognizable trace languages. In this talk I will give an introduction to this theory, starting from the basics. This will include grammars and automata for monoidal languages, a pumping lemma, results on determinization, algebraic recognizability, and applications to Mazurkiewicz trace languages and asynchronous automata. Time permitting, we will outline work in progress on the context-free theory.
