SUMMARY
The discussion centers on the eigenvalues and eigenspaces associated with the transformation T, which reflects points across a line through the origin in R². The eigenvalues identified are -1 and 1, with the eigenspace defined as the set of all eigenvectors corresponding to these eigenvalues, including the zero vector. It is clarified that the basis of the eigenspace is composed of selected eigenvectors, and that the choice of eigenvectors affects the span of the eigenspace.
