Abstract:

In this paper, it is established that the weighted end-point estimates for the commutator of fractional integrals on the spaces of homogenesous type, i.e.,
w({xX:|[b, Iα]f(x)|>t})≤Cψ(∫X A(||b||* |f(x)|/Θ(w(x))dμ(x)),
where b ∈BMO(X, dμ), A(t)=tlog(e+t), ψ(t)=[tlog(e+tα]1/1-α, Θ(t)=t1-αlog(e+t).

Key words: Fractional integral operator, Commutator, Spaces of homogeneous type, Fractional maximal operator, Fractional Orlicz , maximal operator
