On the combinatorial structure of graphs with a spectral idempotent of small dual diameter

Edwin R. van Dam, Giusy Monzillo, Safet PenjiÄ

Let $I^$ be a connected regular graph with an eigenvalue $I^»$ and corresponding idempotent $E_{I^} »$ . Let $E_{I^} » = ⟨ J, E_{I^} » ⟩^{\circ}$ be the algebra generated by $J$ and…

On the $Q$ -polynomial property of bipartite graphs admitting a uniform structure

Blas FernÃ¡ndez, Roghayeh Maleki, Å tefko MiklaviÄ +1

Let $I^$ denote a finite, connected graph with vertex set $X$ . Fix $x \in X$ and let $ε \geq 3$ denote the eccentricity of $x$ . For mutually distinct scalars $\{Î¸^*_i\}_{…
