If a x b 0 then either a 0 or b 0

WebIf a and b are real or complex numbers such that ab = 0, then either a = 0 or b = 0. Does this property hold for matrices? That is, if A and B are n \times n n×n matrices such that \mathbf {A B}=\mathbf {0}, AB= 0, is it true that we must have A = 0 or B = 0? Prove the result or find a counterexample.

WebEither ∣a∣ = 0 or ∣b∣ = 0. Solution: Given that, a ⋅b = 0. Then, either ∣a∣ = 0 or ∣b∣ = 0 or a ⊥ b (in case a and b are non-zero) and if a× b = 0 then either ∣a∣ = 0 or ∣b∣ = 0 or a∥b (in … WebWe shall define " a is greater than b " to mean: a − b is positive. Algebraically: a > b if and only if a − b > 0. On the basis of this definition, we can prove various theorems about inequalities. Theorem 1. We may add the same number to both sides of an inequality, and the sense will not change.
