Developments in Language Theory

This book constitutes the refereed proceedings of the 28th International Conference on Developments in Language Theory, DLT 2024, held in Göttingen, Germany, during August 1216, 2024.

The 17 full papers and 4 invited papers included in this book were carefully reviewed and selected from 26 submissions. They presented current developments in formal languages and automata. The scope is very general and includes, among others, the following topics and areas: grammars, acceptors and transducers for words; trees and graphs; relations between formal languages and artificial neural networks; algebraic theories of automata; algorithmic, combinatorial, and algebraic properties of words and languages; variable length codes; symbolic dynamics; cellular automata; groups and semigroups generated by 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; and quantum computing.
