Resistance Distance and Linearized Optimal Transport on Graphs
Proves that the squared discrete transportation distance between nearby measures on a connected graph is bounded by the quadratic form of a reweighted Laplacian pseudoinverse, yielding a resistance distance with multiple characterizations and showing the random walk as gradient flow on the resulting
