    Let λ > 0 and Δλ:=−d2dx2−2λxddx be the Bessel operator on R+:= (0,∞). We first introduce and obtain an equivalent characterization of CMO(R+, xdx). By this equivalent characterization and by establishing a new version of the Fréchet-Kolmogorov theorem in the Bessel setting, we further prove that a function b ∈ BMO(R+, xdx) is in CMO(R+, xdx) if and only if the Riesz transform commutator xxxx is compact on Lp(R+, xdx) for all p ∈ (1,∞).
