Title: Left Semi-Braces and the Yang-Baxter equation

Supervisor: Prof. Francesco Catino

Final Judgement: cum laude

Description: My thesis focuses on studying set-theoretical solutions of the Yang-Baxter equation via a new algebraic structure called semi-braces.
In 1992, Drinfel'd introduced set-theoretical solutions, posed the question of finding all of these solutions and suggested to narrow solutions that are also involutive. In 2007, Rump presented braces (a ring-like structure) to answer Drinfel'd question in the involutive case using group-theoretical and ring-theoretical tools.
In my thesis, I introduced semi-braces that cover, as a particular case, braces and allows obtaining solutions that are left non-degenerate. In the first chapter, I gave the notion of semi-braces. Then, in the next chapter, I presented the asymmetric product of semi-braces, a new technique for obtaining several examples of semi-braces. In the third chapter, I introduced the matched product of solutions a novel construction technique of semi-braces that allow analyzing the solution associated with a semi-brace. Finally, in the last chapter, I focused on the application of semi-brace in two fields: the Yang-Baxter equation and regular subgroups. In the first part of this chapter, I proved that every semi-brace leads to a solution. Whereas, in the second part, we advance the connection between semi-brace and regular subgroups of the holomorph. I use a particular semi-braces, the braces over a field, to answer the problem of finding regular subgroups of the affine group posed by Liebeck, Praeger, and Saxl.

Research project: ”Yang-Baxter equation and related algebric structures”.

Scientific advisor: Prof. Francesco Catino

Introduced a novel construction technique for set-theoretical solutions of the Yang-Baxter equation that to obtain new classes of involutive and idempotent solutions. This technique led to characterizing completely the solutions associated with a finite semi-brace.
