Query: More elementary operators that are spectrally bounded   We discuss some necessary and some sufficient conditions for an elementary
operator $x\mapsto\sum_{i=1}^n a_ixb_i$ on a Banach algebra $A$ to be
spectrally bounded. In the case of length three, we obtain a complete
characterisation when $A$ acts irreducibly on a Banach space of dimension
greater than three.
