1-forms

Name: Anonymous 2008-04-02 22:38

Can anyone give me a somewhat simplistic explanation of 1-forms?  For some reason I'm really stuck on this, I understand that they're a linear transformation mapping point and a vector to R.  (I'm guessing they actually map to all of C but for sake of learning I'd appreciate it simplified as my understanding of complex analysis is virtually nonexistant at this point in time.)  I don't even understand their purpose, except that a differential is a type of 1-form.  The wikipedia article was a bit over my head & the wolfram article wasn't much help either.

Thanks for responding.  Could you give me an explanation of what a differential is, without recursing? (ie, I've seen a lot of people shrug it of with df = dx + dy + dz or something similar & that explains nothing for me)
