On the Riesz potential and its commutators on generalized Orlicz-Morrey spaces
We consider generalized Orlicz-Morrey spaces M_{\Phi,\varphi}(\Rn)
including their weak versions WM_{\Phi,\varphi}(\Rn). In these spaces we
prove the boundedness of the Riesz potential from M_{\Phi,\varphi_1}(\Rn) to
M_{\Psi,\varphi_2}(\Rn) and from M_{\Phi,\varphi_1}(\Rn) to
WM_{\Psi,\varphi_2}(\Rn). As applications of those results, the boundedness
of the commutators of the Riesz potential on generalized Orlicz-Morrey space is
also obtained. In all the cases the conditions for the boundedness are given
either in terms of Zygmund-type integral inequalities on

Boundedness of intrinsic square functions and their commutators on generalized weighted Orlicz-Morrey spaces
We shall investigate the boundedness of the intrinsic square functions and
their commutators on generalized weighted Orlicz-Morrey spaces
. In all the cases, the conditions for the
boundedness are given in terms of Zygmund-type integral inequalities on weights

Characterizations of Lipschitz functions via the commutators of maximal function in Orlicz spaces on stratified Lie groups
We give necessary and sufficient conditions for the boundedness of the
maximal commutators , the commutators of the maximal operator
and the commutators of the sharp maximal operator in Orlicz
spaces on any stratified Lie group when
belongs to Lipschitz spaces . We obtain some
new characterizations for certain subclasses of Lipschitz spaces

Sobolev-Morrey Type Inequality for Riesz Potentials, Associated with the Laplace-Bessel Differential Operator
2000 Mathematics Subject Classification: 42B20, 42B25, 42B35We consider the generalized shift operator, generated by the Laplace-
Bessel differential operator [...] The Bn -maximal functions and the Bn - Riesz potentials, generated by the Laplace-Bessel differential operator ∆Bn are investigated. We study the Bn - Riesz potentials in the Bn - Morrey spaces and Bn - BMO spaces. An inequality of Sobolev - Morrey type is established for the Bn - Riesz potentials.* This paper has been partially supported by Grant of Azerbaijan-U.S. Bilateral Grants Program (Project ANSF Award / 3102)
Boundedness of the maximal operator and its commutators on vanishing generalized Orlicz-morrey spaces
We prove the boundedness of the Hardy-Littlewood maximal operator and their commutators with BMO-coefficients in vanishing generalized Orlicz-Morrey spaces VM Phi,phi(R-n) including weak versions of these spaces. The main advance in comparison with the existing results is that we manage to obtain conditions for the boundedness not in integral terms but in less restrictive terms of supremal operators involving the Young function Phi(u) and the function phi(x, r) defining the space. No kind of monotonicity condition on phi(x, r) in r is imposed.Ahi Evran University [PYO.FEN.4003.13.003, PYO.FEN.4001.14.017]; Science Development Foundation under Republic of Azerbaijan [EIF-2013-9(15)-46/10/1]; Russian Fund of Basic Research [15-01-02732
