Introduction to classical and quantum integrability

AL Retore - Journal of Physics A: Mathematical and Theoretical, 2022 - iopscience.iop.org
In these lecture notes we aim for a pedagogical introduction to both classical and quantum
integrability. Starting from Liouville integrability and passing through Lax pair and r-matrix …

Skew braces: a brief survey

L Vendramin - Workshop on Geometric Methods in Physics, 2022 - Springer
Our primary focus is on the theory of skew braces, specifically exploring their connection
with combinatorial solutions to the Yang–Baxter equation. Skew braces have recently …

Superintegrable cellular automata and dual unitary gates from Yang-Baxter maps

T Gombor, B Pozsgay - SciPost Physics, 2022 - scipost.org
We consider one dimensional block cellular automata, where the local update rules are
given by Yang-Baxter maps, which are set theoretical solutions of the Yang-Baxter …

Soliton interactions and Yang–Baxter maps for the complex coupled short‐pulse equation

V Caudrelier, A Gkogkou… - Studies in Applied …, 2023 - Wiley Online Library
The complex coupled short‐pulse equation (ccSPE) describes the propagation of ultrashort
optical pulses in nonlinear birefringent fibers. The system admits a variety of vector soliton …

On the passage from finite braces to pre-Lie rings

A Smoktunowicz - Advances in Mathematics, 2022 - Elsevier
Let p be a prime number. We show that there is a one-to-one correspondence between the
set of strongly nilpotent braces and the set of nilpotent pre-Lie rings of cardinality pn, for …

Near braces and pp‐deformed braided groups

A Doikou, B Rybołowicz - Bulletin of the London Mathematical …, 2024 - Wiley Online Library
Motivated by recent findings on the derivation of parametric noninvolutive solutions of the
Yang–Baxter equation, we reconstruct the underlying algebraic structures, called near …

Set-theoretic Yang–Baxter equation, braces and Drinfeld twists

A Doikou - Journal of Physics A: Mathematical and Theoretical, 2021 - iopscience.iop.org
We consider involutive, non-degenerate, finite set-theoretic solutions of the Yang–Baxter
equation (YBE). Such solutions can be always obtained using certain algebraic structures …

From braces to Hecke algebras and quantum groups

A Doikou, A Smoktunowicz - Journal of Algebra and Its Applications, 2023 - World Scientific
We examine links between the theory of braces and set-theoretical solutions of the Yang–
Baxter equation, and fundamental concepts from the theory of quantum integrable systems …

A new formula for Lazard's correspondence for finite braces and pre-Lie algebras

A Smoktunowicz - Journal of Algebra, 2022 - Elsevier
In this paper a simple algebraic formula is obtained for the correspondence between finite
right nilpotent F p-braces and finite nilpotent pre-Lie algebras. This correspondence agrees …

Algebraic approach to Rump's results on relations between braces and pre-Lie algebras

A Smoktunowicz - Journal of Algebra and Its Applications, 2022 - World Scientific
In 2014, Wolfgang Rump showed that there exists a correspondence between left nilpotent
right ℝ-braces and pre-Lie algebras. This correspondence, established using a geometric …
