Ricci curvature of Bruhat orders
Viola Siconolfi
We study the Ricci curvature of the Hasse diagrams of the Bruhat order of finite irreducible Coxeter groups. For this purpose we compute the maximum degree of these graphs for type…

Ricci curvature, Bruhat graphs and Coxeter groups
Viola Siconolfi
We consider the notion of discrete Ricci curvature for graphs defined by Schmuckenschl{ä}ger \cite{shmuck} and compute its value for Bruhat graphs associated to finite Coxeter grou…

Ricci curvature, graphs and eigenvalues
Viola Siconolfi
We express the discrete Ricci curvature of a graph as the minimal eigenvalue of a family of matrices, one for each vertex of a graph whose entries depend on the local adjaciency st…
