Three revolutions in the kernel are worse than one
Abstract
An example is constructed of a purely unrectifiable measure $μ$ for which the singular integral operator whose kernel triples and reverses the argument of a complex number is bounded $L^2(μ)$. This is in sharp contrast with the results known for the Cauchy transform, whose kernel reverses the argument of a complex number.
