comment Basic Properties of Integrals
What is definition of existence $\int f\, d\mu$ ? I thought the integral first is defined for $f>0$.

comment How to test convergence of complex series?
It looks like you had mean $i^n = (-1)^{n+1}i$. But it is not true.

You are right. Maybe it is possible to find continuous representation for such mappinngs. In your example $\phi$ has the continuous representation.
