Homework Help: Product of Dirac delta functions

  1. Jun 6, 2016 #1
    • OP warned about not having an attempt at a solution
    1. The problem statement, all variables and given/known data


    where 'z' is a complex variable 'z0' is a complex number
    Formula is just enough, derivation is not needed.

    The Dirac delta is a distribution, not a number or a function from one number field to another.
    The product of distributions is not in general well defined, see here. You can multiply a distribution by a smooth function, but not in general by another distribution.
    So the expressions above do not have a clear meaning. They are not well-defined.
