Abstract

We consider convolution operators on of the form

, where is a polynomial defined on with values in and is a smooth Calderón-Zygmund kernel on . A maximal operator can be constructed in a similar fashion. We discuss weak-type 1-1 estimates for and and the uniformity of such estimates with respect to . We also obtain -estimates for "supermaximal" operators, defined by taking suprema over ranging in certain classes of polynomials of bounded degree.
