Call for Papers - DLT 2021

The 25th International Conference on Developments in Language Theory (DLT 2021) will take place in Porto, Portugal on August 16-20, 2021.

The purpose of this conference is to bring together members of the academic, research, and industrial community who have an interest in formal languages, automata theory, and related areas.


Due to possible travel restrictions the conference is planned to be held hybrid, with in-person and remote participation. However, the organisers together with the Steering Committee will continue to monitor the pandemic situation.


Typical topics include, but are not limited to, grammars, acceptors and transducers for words, trees and graphs, algebraic theories of automata; algorithmic, combinatorial and algebraic properties of words and languages; variable length codes; symbolic dynamics; cellular automata; polyominoes and multidimensional patterns; decidability questions; image manipulation and compression; efficient text algorithms; relationships to cryptography, concurrency, complexity theory and logic; bio-inspired computing; quantum computing.
