WebJun 9, 2024 · 1 I found out an interesting property of a trace 0 matrix. Suppose A be a n × n matrix whose trace is 0. Then A 2 will be a scalar matrix (that is A 2 is of the form λ I n, where λ is any real constant and I n is the identity matrix ) iff n = 2 .But however, this result does not hold true for n ≥ 3 .
