Abstract:

We discuss weak type inequalities for maximal and fractional integral operators on generalized Morrey spaces over metric measure spaces. Here the measure satisfies the so called growth condition. By taking into account the maximal operator, we obtain a Hedberg type inequality, which leads us to the weak type inequality for the fractional integral operator on the same spaces.

Abstract:

We prove in this paper the necessary and sufficient conditions for the boundedness of the fractional integral operators on Lebesgue spaces over commutative hypergroups. The necessity proofs take into account the Haar measure, meanwhile the sufficiency proofs employ the maximal operators.

We present in this paper some inequalities for the generalized Riesz potential on the generalized Morrey spaces over commutative hypergroups. The results can be found by employing the maximal operator.
