If the Laurent expansion of f contains a finite number of terms in?
Q: If the Laurent expansion of f(z) contains a finite number of terms in the principal part, then what is the singular point called? Firstly, it depends on whether the expansion is in a deleted disk about the point. Assuming that, If finite includes zero, then it might not be a singular point at all, and if it is, it is removeable. Otherwise, it is a pole, of order the smallest negative index.
