Abstract

We present rational Lax representations for one-component parametric quadrirational Yang-Baxter maps in both the abelian and non-abelian settings. We show that from the Lax matrices of a general class of non-abelian involutive Yang-Baxter maps (K\mathcal{K}-list), by considering the symmetries of the K\mathcal{K}-list maps, we obtain compatible refactorization problems with rational Lax matrices for other classes of non-abelian involutive Yang-Baxter maps (Λ\Lambda, H\mathcal{H} and F\mathcal{F} lists). In the abelian setting, this procedure generates rational Lax representations for the abelian Yang-Baxter maps of the FF and HH lists. Additionally, we provide examples of non-involutive (abelian and non-abelian) multi-parametric Yang-Baxter maps, along with their Lax representations, which lie outside the preceding lists.
