Abstract

Convolution type Calder\\'on-Zygmund singular integral operators with rough\nkernels $\\pv \\Om(x)/|x|^n$ are studied. A condition on $\\Om$ implying that the\ncorresponding singular integrals and maximal singular integrals map $L^p \\to\nL^p$ for $1<p<\\nf$ is obtained. This condition is shown to be different from\nthe condition $\\Om\\in H^1(\\sn)$.\n
