Abstract

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 Yang–Baxter maps, expressed in non-commutative variables. In detail, we show that factorizations of order N = 2 matrices of this specific class are equivalent to the homogeneous normalization map . From order N = 3 matrices, we obtain an extension of the homogeneous normalization map, as well as novel entwining pentagon, reverse-pentagon and Yang–Baxter maps.

矩阵因式分解和五边形映射
我们提出了一类特殊的矩阵,它们参与的因式分解问题等价于恒定和缠绕(非恒定)五边形、反五边形或杨-巴克斯特映射,用非交换变量表示。具体而言,我们证明了这一特定类别的 N = 2 阶矩阵的因式分解等价于同质归一化映射。从 N = 3 阶矩阵中,我们得到了同质归一化映射的扩展,以及新颖的缠绕五边形、反五边形和杨-巴克斯特映射。
