SUMMARY
The discussion centers on proving that for a nilpotent matrix A, the determinants satisfy the equations det(I-A) = det(I+A) = 1. It is established that since A is nilpotent, det(A) = 0 and det(I) = 1. The trace of A, tr(A), is zero, leading to the conclusion that tr(I-A) and tr(I+A) both equal n. The hint provided suggests utilizing the property (I + A)² to further explore the determinants.
