Is there a good general definition of [itex]0^z[/itex], where z may be complex? The cases where z is real (and positive, negative, or zero) are straightforward, but what if z isn't real? Are there arbitrary branch cuts involved, or is there some universal definition?(adsbygoogle = window.adsbygoogle || []).push({});
