Hamilton's Ricci flow is a (weakly parabolic) geometric evolution equation, which deforms a given Riemannian metric in its most natural direction. Over the last decades, it has been used to prove ...

They appear in a very natural manner in many areas of mathematics and physics. On a differential manifold or more generally on a geodesic metric space, one investigates geometric and analytic ...

Another innovative technique is Discrete Metric Learning (DML), which leverages the Riemannian manifold to facilitate fast image set classification. By minimizing the Hamming distance between ...
