The critical exponent: a novel graph invariant

Dominique Guillot, Apoorva Khare, Bala Rajaratnam

A surprising result of FitzGerald and Horn (1977) shows that $A^{\circ α} := (a_{ij}^{α})$ is positive semidefinite (p.s.d.) for every entrywise nonnegative $n \times n$ p.s.d. matri…

A combinatorial model for computing volumes of flow polytopes

Carolina Benedetti, Rafael S. González D'León, Christopher R. H. Hanusa +4

We introduce new families of combinatorial objects whose enumeration computes volumes of flow polytopes. These objects provide an interpretation, based on parking functions, of Bal…
