comment How to prove a $k$-$1$ differential form is simple
@ReneSchipperus Hm? I see they must be a linear combination of the $k$ linearly independent $k$-$1$ forms, but I don't see it. I promise I've given it many thoughts. And the fact I've always seen it stated without proof makes me feel stupid xD

@ReneSchipperus Yes, but is that enough? I don't see it.

comment Book recommendations for someone interested in higher mathematics?
I first learnt group theory (only finite groups), then topology, and then more group theory (more about representation theory and continous groups). As for analysis, I've never learnt more than what a regular physicist studies, and I notice a lack of knowledge I would like to get rid off :)

comment Book recommendations for someone interested in higher mathematics?
I'm also a physicist (student), and Munkres' Topology is the book I used to learn about it. I don't know the other two, but that one is, in my opinion, great. Very understandable, and everything is greatly explained. I really recommend it.

That calculation was exactly what I needed. It's clear now, thank you.

No, but the curvature tensor $R$ is $0$, and I want to calculate $R'$-
