review text: The authors obtain some new sphere theorems using Ricci flow. This means that if for some Riemannian \(n\)-manifold certain curvature pinching conditions are satisfied, then \(M\) is diffeomorphic to the sphere \(\mathbb{S}^n\). Besides its clarity, the article has a nice introduction to the subject.
