Abstract.
We prove the strong-type and weak-type estimates for the Calderón--Zygmund singular integrals on central Morrey--Orlicz and weak central Morrey--Orlicz spaces defined in our earlier paper [26]. Next part has similar investigations between distinct central Morrey--Orlicz and weak central Morrey--Orlicz spaces. Then we define the $\lambda$-central mean oscillation--Orlicz spaces and its weak version investigating also some estimates for a modified Calderón--Zygmund singular integrals. Also, we show boundedness of a modified Calderón--Zygmund singular integrals from central Morrey--Orlicz spaces to $\lambda$-central mean oscillation--Orlicz spaces, even for different Orlicz functions, and corresponding weak version.
