1. A branch of differential geometry that studies curved spaces and generalizes Euclidean geometry using Riemannian metrics, developed by Bernhard Riemann
Riemannian geometry is fundamental to Einstein's theory of general relativity
A geometria riemanniana é fundamental para a teoria da relatividade geral de Einstein
2. The mathematical framework for understanding manifolds with a metric tensor that allows measurement of distances and angles
In Riemannian geometry, geodesics are the analogues of straight lines
Na geometria riemanniana, as geodésicas são os análogos das linhas retas
