Mathematical Sciences Departmental Seminar
These Departmental Seminars are for everyone interested in Maths. We encourage anyone interested in the subject in general, or in the particular subject of the seminar, to come along. It's a great opportunity to meet people in the Maths Department and join in with our community.
Refreshments are shared in the Department (STEM 5.1) after every seminar.
We study some solutions of the set-theoretic parametric Yang-Baxter equation. These solutions are bi-rational maps with several invariants and a Lax representation . We show that we can use these maps as building blocks in order to construct higher dimensional bi-rational maps which have nice properties and we prove their integrability in the Liouville sense. These maps can be seen as higher dimensional generalisations of the famous integrable QRT maps , known as Adler's Triad maps . Finally, we discuss some new generalisations .
