Determining finite connected graphs along the quadratic embedding constants of paths

Determining finite connected graphs along the quadratic embedding constants of paths

The QE constant of a finite connected graph G, denoted by QEC(G), is by definition the maximum of the quadratic function associated to the distance matrix on a certain sphere of codimension two. We prove that the QE constants of paths Pn form a strictly increasing sequence converging to −1/2. Then w...
