Hello everyone, I'm new to this forum.(adsbygoogle = window.adsbygoogle || []).push({});

I have a doubt about differential forms, related to the divergence.

On a website I read this:

"In general, it is true that in R^3 the operation of d on a differential 0-form gives the gradient of that differential 0-form, that on a differential 1-form give the curl of that differential 1-form, and that on a differential 2-form gives its divergence."

My question is: In R^2 how can I obtain de 2-d version of the divergence by differentiating a form? Because if I differentiate a 0-form it gives me the 2-d version of the gradient, and if I differentiate a 1-form it gives me the 2-d version of the curl.
