WebDec 13, 2024 · Conversely, every n × n matrix that is both idempotent and symmetric is a projection matrix (specifically, it is the projection matrix for its column space). Note. … WebFeb 11, 2024 · Their algebraic connections were considered. It was shown that the core of a RBL is elastic and right idempotent. The core of a RBL was found to be alternative (or left idempotent) if and only if its corresponding MBL is right symmetric. If a MBL is right (left) symmetric, then, the core of its corresponding RBL is a medial (semimedial).
