Course objectives
The course presents two closely related areas of theoretical computer science and mathematics: theory of regular languages and finite semigroups.
Learning outcomes
After passing the course, students will: be familiar with modern methods of the theory of regular languages; understand the connection between classes of regular languages and finite semigroups; be able to use pseudovarieties of semigroups to describe properties of regular languages; master basic notions and techniques of the structure theory of finite semigroups.
  • 1. Recognizable and rational sets: definitions, relations between them, closure properties.
  • 2. Structure of finite semigroups: Green's relations, 0-simple semigroups, factorization forests.
  • 3. Eilenberg correspondence: pseudovarieties, pseudoidentities, examples.
  • 4. Well quasiorders in formal language theory.
