Bilinear fractional Hardy-type operators with rough kernels on central Morrey spaces with variable exponents

Hongbin Wang, Chenchen Niu (2024)

Czechoslovak Mathematical Journal

Similarity:

We introduce a type of n -dimensional bilinear fractional Hardy-type operators with rough kernels and prove the boundedness of these operators and their commutators on central Morrey spaces with variable exponents. Furthermore, the similar definitions and results of multilinear fractional Hardy-type operators with rough kernels are obtained.

Trace inequalities for fractional integrals in grand Lebesgue spaces

rning the boundedness for fractional maximal and potential operators defined on quasi-metric measure spaces from L p ) , θ ( X , μ ) to L q ) , q θ / p ( X , ν ) (trace inequality), where 1 < p < q < ∞, θ > 0 and μ satisfies the doubling condition in X. The results are new even for Euclidean spaces. For example, from our general results D. Adams-type necessary and sufficient conditions guaranteeing the trace inequality for fractional maximal functions and potentials defined on so-called s-sets in ℝⁿ follow. Trace...

On conditions for the boundedness of the Weyl fractional integral on weighted L p spaces

Liliana De Rosa, Alberto de la Torre (2004)

Commentationes Mathematicae Universitatis Carolinae

Similarity:

In this paper we give a sufficient condition on the pair of weights ( w , v ) for the boundedness of the Weyl fractional integral I α + from L p ( v ) into L p ( w ) . Under some restrictions on w and v , this condition is also necessary. Besides, it allows us to show that for any p : 1 ≤ p < ∞ there exist non-trivial weights w such that I α + is bounded from L p ( w ) into itself, even in the case α > 1 .

Fractional Hardy-Sobolev-Maz'ya inequality for domains

Bartłomiej Dyda, Rupert L. Frank (2012)

Studia Mathematica

Similarity:

We prove a fractional version of the Hardy-Sobolev-Maz’ya inequality for arbitrary domains and L p norms with p ≥ 2. This inequality combines the fractional Sobolev and the fractional Hardy inequality into a single inequality, while keeping the sharp constant in the Hardy inequality.

Weighted endpoint estimates for commutators of fractional integrals

David Cruz-Uribe, Alberto Fiorenza (2007)

Czechoslovak Mathematical Journal

Similarity:

Given α , 0 < α < n , and b ∈ B M O , we give sufficient conditions on weights for the commutator of the fractional integral operator, [ b , I α ] , to satisfy weighted endpoint inequalities on ℝ n and on bounded domains. These results extend our earlier work [3], where we considered unweighted inequalities on ℝ n .
