| In this thesis,we mainly analyse the problem of operator inequalities of Morrey spaces associated with Karamata regular variation.And we also introduce the relation between central Morrey spaces,Herz spaces and Morrey-Herz spaces with variable exponent.For an applications,We will establish the boundedness for the homogeneous fractional integral operator TΩ,σ and its commutator[b,TΩ,σ]on the Morrey-Herz space with variable exponent.The main contents of the thesis consist of four chapters:The first chapter includes three parts,in the first paxt,we introduce the origin and basic definition of morrey space.In the second part,we give the research definition of weight function(w∈ Ap)and its properties.In the third and fourth parts,we introduce the definitions and the existing research results of weighted Morrey spaces and one-sided operators,respectively.In the fifth part,we introduce the boundedness of one-sided operator on Morrey space which associated with Karamata regular variation.In the sixth part,the work of this thesis is briefly introduced.In the second chapter,one-sided operator on Morrey space associated with Karama-ta regular variation axe considered.There are three parts in this chapter.In the first part,we present a few related lemmas.In the next part,We studied the boundedness of one-sided operator on one-dimensional Morrey space associated with.Karamata regular vari-ation.Finally,the boundedness of operators on n-dimensional Morrey space associated with Karamata regular variation are considered.In chapters three,we will give the relation between central Morrey spaces,Herz spaces and Morrey-Herz spaces with variable exponent.For an applications,We will establish the boundedness for the homogeneous fractional integral operator TΩ,σ and its commutator[b,TΩ,σ]on the Morrey-Herz space with variable exponent.In the last chapter,we summarize the main work of the thesis,and give some suggestions and expectations to the research in future. |
