in the .pdf article http://repository.dl.itc.u-tokyo.ac.jp/dspace/bitstream/2261/6027/1/jfs080104.pdf
i have found the strange representation
[tex] \delta (x) = -\frac{1}{2i \pi} [z^{-1}]_{z=x} [/tex]
and a similar formula for Heaviside function replacing 1/z by log(-z) , what is the meaning ? of this formula
