Maximal and Calderon-Zygmund operators on the local variable Morrey-Lorentz spaces and some applications

A. Kucukaslan, V. S. Guliyev, C. Aykol +1

In this paper, we give the definition of local variable Morrey Lorentz spaces which are a new class of functions. Also, we prove the boundedness of the Hardy Littlewood maximal ope…

On the Riesz potential and its commutators on generalized Orlicz-Morrey spaces

Vagif S. Guliyev, Fatih Deringoz

We consider generalized Orlicz-Morrey spaces $M_{Φ,φ}(\Rn)$ including their weak versions $WM_{Φ,φ}(\Rn)$. In these spaces we prove the boundedness of the Riesz potential from $M_{…

Maximal, potential and singular operators in the local "complementary" variable exponent Morrey type spaces

Vagif S. Guliyev, Javanshir J. Hasanov, Stefan G. Samko

We consider local "complementary" generalized Morrey spaces ${\dual \cal M}_{\{x_0\}}^{p(\cdot),\om}(\Om)$ in which the -means of function are controlled over $\Om\backslash B(x…
