Pal's permanent conjecture: proof for block uniform matrices

Andrea Ottolini, Shannon Starr

Consider a symmetric function $C (x, y)$ on $[0, 1] \times [0, 1]$ which is twice continuously differentiable up to the boundary, and which satisfies $ \mathcal{C}(x,y)=\mathca…

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…

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…
