I am looking for resources or places where where I can see a proof of that. I have read Loring W Tu books on manifolds and differential geometry respectively and I know of Hall book on Lie GRoups but I am looking for something that is still accessible but covers abstract groups not just subsets of $\mathfrak{R}^n$
