On the boundedness of the maximal operator and singular integral operators in generalized Morrey spaces

Similarity:

In the paper we find conditions on the pair ( ω 1 , ω 2 ) which ensure the boundedness of the maximal operator and the Calderón-Zygmund singular integral operators from one generalized Morrey space p , ω 1 to another p , ω 2 , 1 < p < , and from the space 1 , ω 1 to the weak space W 1 , ω 2 . As applications, we get some estimates for uniformly elliptic operators on generalized Morrey spaces.

Boundedness of some sublinear operators and commutators on Morrey-Herz spaces with variable exponents

Similarity:

We introduce a new type of variable exponent function spaces M K ˙ q , p ( · ) α ( · ) , λ ( n ) of Morrey-Herz type where the two main indices are variable exponents, and give some propositions of the introduced spaces. Under the assumption that the exponents α and p are subject to the log-decay continuity both at the origin and at infinity, we prove the boundedness of a wide class of sublinear operators satisfying a proper size condition which include maximal, potential and Calderón-Zygmund operators and their commutators...

Let M β be the fractional maximal function. The commutator generated by M β and a suitable function b is defined by [ M β , b ] f = M β ( b f ) - b M β ( f ) . Denote by 𝒫 ( n ) the set of all measurable functions p ( · ) : n [ 1 , ) such that 1 < p - : = ess inf x n p ( x ) and p + : = ess sup x n p ( x ) < , and by ( n ) the set of all p ( · ) 𝒫 ( n ) such that the Hardy-Littlewood maximal function M is bounded on L p ( · ) ( n ) . In this paper, the authors give some characterizations of b for which [ M β , b ] is bounded from L p ( · ) ( n ) into L q ( · ) ( n ) , when p ( · ) 𝒫 ( n ) , 0 < β < n / p + and 1 / q ( · ) = 1 / p ( · ) - β / n with q ( · ) ( n - β ) / n ( n ) .
