Abstract:In this paper, we establish the boundedness of the following maximal operator

$$Mf(x,x_n ) = \mathop {\sup }\limits_{r > 0} \left\{ {\frac{1}{{r^{n - 1} }}\int_{\left| y \right| \leqslant r} {\left| {f(x - y,x_n  - \Gamma (y))} \right|dy} } \right\}(x,y \in R^{n - 1} ,x_n  \in R)$$
onL p (R n ) for allp>1, n≥2, where Γ(y)≡Γ(|y|) is a real, measurable, and radial function defined onR n−1 .
