Hardy–Littlewood fractional maximal operators on homogeneous trees [PDF]

We study the mapping properties of the Hardy–Littlewood fractional maximal operator between Lorentz spaces of the homogeneous tree and discuss the optimality of all the ...

Boundedness and Sobolev-Type Estimates for the Exponentially Damped Riesz Potential with Applications to the Regularity Theory of Elliptic PDEs

Fractal and Fractional
This paper investigates a new class of fractional integral operators, namely, the exponentially damped Riesz-type operators within the framework of variable exponent Lebesgue spaces Lp(·).

Hardy-Littlewood Maximal Functions [PDF]

, 1974
The principal object of this study is to find weak and strong type estimates concerning functions in weighted Lp spaces and their maximal functions. We also apply these results to the study of convolution integrals.

Gradient estimate in Orlicz spaces for elliptic obstacle problems with partially BMO nonlinearities

Electronic Journal of Differential Equations, 2018
We prove a global Orlicz estimate for the gradient of weak solutions to a class of nonlinear obstacle problems with partially regular nonlinearities in nonsmooth domains.
