13th International Conference on Words

September 13 — 17, 2021, Rouen, France.

WORDS is a biannual international conference covering the mathematical theory of words (sequences of symbols) from all points of view: combinatorial, algebraic, algorithmic, as well as its applications to biology, linguistics, physics, and others.

The previous WORDS conferences have taken place in Rouen (1997, 1999), Palermo (2001), Turku (2003, 2013), Montreal (2005, 2017), Marseille (2007), Salerno (2009), Prague (2011), Kiel (2015), and Loughborough (2019).

If the Covid situation allows it, the 13th International Conference on Words, WORDS 2021 will take place on September 13th-17th 2021 in Rouen and in some hybrid form. Otherwise, it will be held completely virtually.

Co-chairs of this edition are Thierry Lecroq and Svetlana Puzynina.
