Geodesics and deformed pseudo-Riemannian manifolds with symmetry

2001
Riemannian manifolds whose geodesics are given by explicit formulas are rare and worthy of notice. In this paper by deforming the standard metrics on \(S^n\) or \(\mathbb R^n\) new examples of complete \(n\)-dimensional Riemannian manifolds whose geodesics are expressible in terms of elementary functions are discovered.
