## Main Question or Discussion Point

Trying to get my head around some basic exterior calculus concepts

So #1 - 1-form or covector the grad is a covector / 1-form defined as something that combined with a vector takes it to a scalar, for example divergence is a scalar which is the dot-product of a function with its grad (e.g. a 1-form or covector) - correct?

#2 - is there an correspondance between curl and a wedge product? can curl be written as a wedge product?
