Abstract
We study spectrally bounded elementary operators of length two on a complex unital Banach algebra A. Some related conditions are investigated as well. In particular, we show that if S is an elementary operator of length two such that S(x) is quasi-nilpotent for every x ∈ A, then S(x)3 ∈ radA for every x ∈ A.
