It is well known that the product rule for the exterior derivative reads
d(a\wedge b)=(da)\wedge b +(-1)^p a\wedge (db),where a is a p-form.
In gauge theory we then introduce the exterior covariant derivative D=d+A\wedge. What is then D(a ∧ b) and how do you prove it?
I obtain
D(a\wedge...
In a text I am reading (that I unfortunately can't find online) it says:
"[...] differential forms should be thought of as the basis of the vector space of totally antisymmetric covariant tensors. Changing the usual basis dx^{\mu_1} \otimes ... \otimes dx^{\mu_n} with dx^{\mu_1} \wedge ...
