Abstract
We show that every operator on $L^{p}$, $1 \lt p \lt \infty $, defined by multiplication by the identity function on $\mathbb {C}$ is a compact perturbation of an operator that is diagonal with respect to an unconditional basis. We also classify these operators up to similarity modulo compact operators and up to approximate similarity.
