Math for physicists: differential forms
The above site says
“This is supposed to be a self-contained exposition for someone who has some knowledge of multivariable calculus.”
Now I’ve self studied multivariable calculus but this site immediately launches into wedge products p-forms, p-surfaces etc. What am I missing I’ve never even heard of these things. Did I use the wrong text for multivariable calculus?
