Algebraic structures and linear maps form a cornerstone in modern mathematics, underpinning areas as diverse as abstract algebra and functional analysis. Algebraic structures such as groups, rings, ...
Linear algebra with more rigour and depth than at Level 1. Elementary field theory, vector spaces over arbitrary fields, linear transformations and matrices. The determinant is defined rigorously, ...
Abstract. In this paper, we present the explicit expression for the group inverse of the sum of two matrices. As an application, the explicit expression for the group ...
