Özet
In the article we consider the fractional maximal operator M α, 0≤ α< Q on any Carnot group G (ie, nilpotent stratified Lie group) in the generalized Morrey spaces M p, φ (G), where Q is the homogeneous dimension of G. We find the conditions on the pair φ 1, φ 2) which ensures the boundedness of the operator M a from one generalized Morrey space M p, φ 1 (G) to another M q, φ 2 (G), 1< p≤ q<∞, 1/p− 1/q= α/Q, and from the space M p, φ 1 (G) to the weak space W M q, φ 2 (G), 1≤ q<∞, 1− 1/q= α/Q. Also find conditions on the φ which ensure the Adams type boundedness of the M a from M p, φ 1 p (G) to M p, φ 1 q (G) for 1< p< q<∞ and from M 1, φ (G) to W M q, φ 1 q (G) for 1< q<∞. In the case b∈ BMO (G) and 1< p< q<∞, find the sufficient conditions on the pair (φ 1, φ 2) which ensures the boundedness of the kth-order commutator operator M b, a, k from M p, φ 1 (G) to M p, φ 2 (G) with 1/p− 1/q= a/Q.
