How does it work, exactly?(adsbygoogle = window.adsbygoogle || []).push({});

Assume I have a vector field function and I take the curl of it.

If I get a curl of zero, then does thatguaranteethat there is no potential function?

And if I get a curl of non-zero, does thatguaranteethat there is a potential function?

I googled this, but it wasn't clear.

Thanks.
