Energy, entropy and the Ricci flow
Joseph Samuel, Sutirtha Roy Chowdhury
The Ricci flow is a heat equation for metrics, which has recently been used to study the topology of closed three manifolds. In this paper we apply Ricci flow techniques to general…

Geometric flows and black hole entropy
Joseph Samuel, Sutirtha Roy Chowdhury
Perelman has given a gradient formulation for the Ricci flow, introducing an ``entropy function'' which increases monotonically along the flow.We pursue a thermodynamic analogy and…

Measuring the general relativistic curvature of wave-fronts
Joseph Samuel
Einstein's general theory of relativity predicts that an initially plane wave-front will curve because of gravity. This effect can now be measured using Very Long Baseline Interfer…
