Could you recommend some beginner books for Riemannian geometry to me?
I am completely new to Riemannian geometry, but have some basic knowledge of differential geometry.
I am looking for a book in Riemannian which is similarly as light as Tu's "Introduction to Manifolds" for differential geometry. I know that the classical reference is the book of do Carmo, but I have heard some students complaining that its not a book for the absolute beginner.
For the moment, I am just looking for a source to introduce me Riemannian metrics, Riemannian manifolds, curvature, geodesics in a way as clear as possible.
Thank you
