I find it sometimes confusing dealing with integrals of multi-valued functions in distinguishing a closed integration path, and an integration path which forms a closed loop over the function. They can of course be quite different. For example:
$$\oint f(z)dz.$$
Now, is the integration to be done simply over any of the multiple sheets, for example random every [itex]\pi/12[/itex] over a circle or, is the integration to be done over an analytically-continuous path over the function?
Why don't we have a special integral symbol for the later?
