In this paper,the study of gradient regularity for solutions of a class of elliptic problem. of p-Laplace type is *** particular,we prove a global result concerning Lorentz-m.rrey regularity of the non-hom.geneous boundary data problem.-div((s^(2)+|▽u|^(2)p-2/2)▽u)=-div(|f|^(p-2)f)+g inΩ,u=h in■Ω,with the(sub-elliptic)degeneracy condition s∈[0,1]and with m.xed data f∈L^(p)(Q;R^(n)),g∈Lp/(p-1)(Ω;R^(n))for p∈(1,n).This problem.naturally arises in various applications such as dynam.cs of non-Newtonian fluid theory,electro-rheology,radiation of heat,plastic m.ulding and m.ny *** on the idea of level-set inequality on fractional m.xim.l distribution functions,it enables us to carry out a global regularity result of the solution via fractional m.xim.l *** to the significance of m.(α)and its relation with Riesz potential,estim.tes via fractional m.xim.l functions allow us to bound oscillations not only for solution but also its fractional derivatives of orderα.Our approach therefore has its own interest.
