Abstract
We study Fourier multipliers and singular integrals on curves and surfaces that are Möbius transformation images of Lipschitz graphs and starlike Lipschitz surfaces. We show that the singular integrals in each case form an operator algebra identical to the bounded holomorphic Fourier multipliers and the Cauchy-Dunford bounded holomorphic functional calculus of the associated Dirac operator in the context considered here.
