Matrix factorizations and pentagon maps

P Kassotakis - Proceedings of the Royal Society A, 2023 - royalsocietypublishing.org
We propose a specific class of matrices that participate in factorization problems that turn out
to be equivalent to constant and entwining (non-constant) pentagon, reverse-pentagon or …

Idempotent set-theoretical solutions of the pentagon equation

M Mazzotta - Bollettino dell'Unione Matematica Italiana, 2024 - Springer
A set-theoretical solution of the pentagon equation on a non-empty set X is a function s: X×
X→ X× X satisfying the relation s 23 s 13 s 12= s 12 s 23, with s 12= s× id X, s 23= id X× s …

Set-theoretical solutions of the Yang–Baxter and pentagon equations on semigroups

F Catino, M Mazzotta, P Stefanelli - Semigroup Forum, 2020 - Springer
Abstract The Yang–Baxter and pentagon equations are two well-known equations of
Mathematical Physic. If S is a set, a map s: S * S → S * S s: S× S→ S× S is said to be a set …

I Colazzo, E Jespers, Ł Kubat - Communications in Mathematical Physics, 2020 - Springer
A set-theoretic solution of the Pentagon Equation on a non-empty set S is a map s: S^ 2 →
S^ 2 s: S 2→ S 2 such that s_ 23 s_ 13 s_ 12= s_ 12 s_ 23 s 23 s 13 s 12= s 12 s 23, where …

On the structure of set-theoretic polygon equations

On commutative set-theoretic solutions of the Pentagon Equation

M Castelli - arXiv preprint arXiv:2404.13758, 2024 - arxiv.org
We extend the so-called retract relation given in [6] for involutive set-theoretic solutions of
the Pentagon Equation and we introduce the notion of associated permutation group to …

On quadrirational pentagon maps

C Evripidou, P Kassotakis, A Tongas - arXiv preprint arXiv:2405.04945, 2024 - arxiv.org
We classify rational solutions of a specific type of the set theoretical version of the pentagon
equation. That is, we find all quadrirational maps $ R:(x, y)\mapsto (u (x, y), v (x, y)), $ where …
