摘要
本文得出了径向核的一个点态恒等逼近定理,并给出了一个有意义的实例以说明本文所得定理推广了Calderon和Zygmund的结果。
In this paper, a theorem about pointwise convergent approximate identity ofradial kernels is presented and a useful example is shown in order to exaplain thatthe theorem in this paper is an extension of the theorem of Calderon and Zygmund.
