Query: On regularity and irregularity of certain holomorphic singular integral
  operators   We survey recent work and announce new results concerning two singular
integral operators whose kernels are holomorphic functions of the output
variable, specifically the Cauchy-Leray integral and the Cauchy-Szeg\H o
projection associated to various classes of bounded domains in $\mathbb C^n$
with $n\geq 2$.
