Ricci curvature: An economic indicator for market fragility and systemic risk.

We are uncovering information similar to that about entropy with two very important caveats: First, the method proposed herein is computationally more tractable and is better behaved than entropy-based techniques; we are simply using an algorithm based on linear programming, which is capable of characterizing curvature between any two nodes in a graph (not only those that are adjacent) to account for possibly significant indirect effects.
