AI中文摘要：
我们对基本GL型R矩阵和任意奇偶序列的Z_2-分级扭反射方程的常数数值解进行了分类，不假设偶性或可逆性。该分类基于为此类反射方程建立的四指标局域性原理。我们确定了奇异解和可逆解，并恢复了最小对称分级下先前推测的矩阵。偶可逆解符合最近的分级Satake图分类。全支撑下三角非偶族的经典稳定化子是一个李超代数，其偶部分是电李代数。
英文摘要：
We classify constant numerical solutions of the $\Z_2$-graded twisted reflection equation for the fundamental $GL$-type R-matrix and an arbitrary parity sequence, without assuming evenness or invertibility. The classification is based on a four-index locality principle established for this type of reflection equation. We determine the singular and invertible solutions and recover previously conjectured matrices for the minimal symmetric grading. Even invertible solutions comply with the recent classification of graded Satake diagrams. The classical stabilizer of a full-support lower-triangular non-even family is a Lie superalgebra whose even part is an electrical Lie algebra.
