1. Semigroup theory
2. Completely 0-simples semigroups
3. Regular semigroups
4. Inverse semigroups

By the end of the course the student should be able to prove Green’s Lemmas, Rees’s theorem and the basic results about inverse semigroups.

1. Local structure of semigroups (the structure of a D-class and Green’s Lemmas).
2. The basic results about inverse semigroups.
3. The structure of the most common ransformation semigroups such as T(X) and I(X).

E-learning.

Continuous assessment is privileged: 2 digital written documents (e-folios) during the semester (40%) and a final digital test, Global e-folio (e-folio G) at the end of the semester (60%). In due time, students can alternatively choose to perform one final exam (100%).
