http://jmi.ele-math.com/09-43/Inequalities-for-the-Frobenius-norm Web16 okt. 2008 · Introduction In [4] we raised the conjecture that the Frobenius norm of the commutator of two real matrices satisfies the inequality ‖XY − YX‖ F √ 2‖X‖ F ‖Y‖ F . (1) We there proved this for real 2× 2 matrices and also showed that the inequality is true with √ 2 replaced by √ 3.
