摘要

Let \(\Phi \) Φ be a locally integrable function, s be a measurable function on \(\mathbb {R}^+\) R + . Then the generalized Hausdorff operator, associated to the parameter curves \(s(x,t):=s(t)x\) s ( x , t ) : = s ( t ) x , is defined by \(\mathcal {H}_{\Phi ,s}f(x)=\int _{\mathbb {R}^n}\frac{\Phi (y)}{|y|^n}f( s(|y|)x )dy. \) H Φ , s f ( x ) = R n Φ ( y ) | y | n f ( s ( | y | ) x ) d y . In this paper, we estabilish the boundedness of the generalized Hausdorff operators \(\mathcal {H}_{\Phi ,s}\) H Φ , s on mixed radial-angular central Morrey spaces. Moreover, we also obtain sufficient and necessary conditions on \(\Phi \) Φ which ensure the boundedness of their commutators on mixed radial-angular central Morrey spaces with symbols in mixed radial-angular central BMO spaces.
