On the sharp estimates for maximal operators
Azamat M. Barakayev Samarkand State University, Samarkand, Uzbekistan
Abstract:
The paper deals with boundedness problem for the maximal operators associated with hypersurfaces in the space of square integrable functions. A necessary condition for boundedness is given in the case of one nonvanishing principal curvature. A criterion for the boundedness is obtained for a particular class of convex hypersurfaces.
Keywords:
maximal operator, Fourier transform, hypersurface, boundedness.
