Week 7, Tuesday 11th November
Edith M. Vargas García Introduction to clones and relational clones
Clones are sets of operations on a fixed domain that are closed under composition and contain all projections. Relational clones can be characterised as those sets of relations on a fixed domain that are closed with respect to primitive positively definable relations. A gentle introduction to clones, relational clones and their Galois theory is given.
