Query: On the boundedness of non-integer dimension Calder\'on-Zygmund Operators
  with antisymmetric kernels   We characterize the non-atomic measures $\mu$ for which all
Calder\'{o}n-Zygmund operators with antisymmetric kernels of a fixed
non-integer dimension $s$ are bounded in $L^2(\mu)$ in terms of a positive
quantity, the Wolff energy.
