   <dim:field mdschema="dc" element="description" qualifier="abstract">In 1952, Calderdn and Zygmund published a paper   in which they discussed a certain kind of singular integral, and used some of their results to establish differential properties of solutions of Poisson&amp;apos;s equation. Recently, Jones made some observations on the fundamental solution  of the heat equation and gave another class of singular integrals. In this thesis it is shown that a special case of Jones&amp;apos;s kernel is of Calderon-Zygmund type and a real, even kernel considered in [2] is a kernel of Jones&amp;apos;s type if the coordinate system is suitably chosen. Moreover,  for such kernels, the difference of the convolution operators-- defined in the sense of Jones and in the sense of CalderonZygmund, respectively--is a constant multiple of the identity operator.</dim:field>
