Consider the case of a linear transformation from Rn to Rm given by ~y = A~x where A is an m × n matrix, the transformation is invert-ible if the linear system A~x = ~y has a unique solution. 1. Case 1: m < n The system A~x = ~y has either no solutions or infinitely many solu-tions, for any ~y in Rm. Therefore ~y = A~x is noninvertible. 2.Let V and W be vector spaces, and T : V !
