On the image of graph distance matrices

William Dudarov, Noah Feinberg, Raymond Guo +5

Let $G = (V, E)$ be a finite, simple, connected, combinatorial graph on $n$ vertices and let $D \in R^{n \times n}$ be its graph distance matrix $D_{ij} = d (v_{i}, v_{j})$ . Stein…

Greedy Matching in Optimal Transport with concave cost

Andrea Ottolini, Stefan Steinerberger

We consider the optimal transport problem between a set of $n$ red points and a set of $n$ blue points subject to a concave cost function such as $c (x, y) = ∥ x - y ∥^{p}$ for $0< p <…

Concentration of Hitting Times in Erdös-Rényi graphs

Andrea Ottolini, Stefan Steinerberger

We consider Erdős-Rényi graphs $G (n, p)$ for $0 < p < 1$ fixed and $n \to \infty$ and study the expected number of steps, $H_{w v}$ , that a random walk started in $w$ needs t…

Central limit theorem in complete feedback games

Andrea Ottolini, Raghavendra Tripathi

Consider a well-shuffled deck of cards of $n$ different types where each type occurs $m$ times. In a complete feedback game, a player is asked to guess the top card from the deck.…

Graph curvature via resistance distance

Karel Devriendt, Andrea Ottolini, Stefan Steinerberger

Let $G = (V, E)$ be a finite, combinatorial graph. We define a notion of curvature on the vertices $V$ via the inverse of the resistance distance matrix. We prove that this notion of…
