Abstract:

A weighted weak type endpoint estimate is established for the maximal operator  associated with the commutator generated by fractional integral operator and BMO function on spaces of homogeneous type. As an application, a two-weight weak type norm inequality for the commutator is obtained.

Key words: Spaces of homogeneous type, Fractional integral, Commutator, Weighted weak type estimate
