WebAug 3, 2024 · Abstract Let R be a unital ring with involution. In Section 2, for given two core invertible elements , we investigate mainly the absorption law for the core inverse in virtue of the equality of the projections and . In Section 3, we study several relations concerning the projections and , where and . Some well-known results are extended to the -reducing … Web3.6. Generalized Inverses 1 Section 3.6. Generalized Inverses Note. For A invertible, the unique solution to the system Ax = b is x = A−1b. We saw in Theorem 3.5.3(1) that if A− is a generalized inverse of A then a solution to Ax = b is x = A−b. In this section we explore the generalized inverse of a matrix and show that such a matrix ...

Webinverse which must coincide with the ordinary inverse A−1. To see this, first observe that A−1 apparently satisfies the definition and thus is a generalized inverse. Conversely,ifA hasageneralizedinverseG,thenfromtheequation AGA = A weget G = A−1(AGA)A−1 = A−1(A)A−1 = A−1 Thisthusjustifiestheterm“generalizedinverse”.
