Description
| - We give an example of commuting pairs A = (A1;A2), B = (B1; B2) of matrices such that AB := (A1B1;A2B2) and BA := (B1A1; B2A2) are commuting pairs but T(AB) , T(BA); moreover, T(AB) n f(z;w) : zw = 0g , T(BA) n f(z;w) : zw = 0g. Further, we show that T(AB) = T(BA) if A and B are criss-cross commuting n-tuples of operators and A is normal. This gives a positive answer to a problem studied in [2].
