The $α$ -representation for the characteristic function of a matroid

Eduard Yu. Lerner

Let $M = (E, B)$ be an $F_{q}$ -linear matroid; denote by $B$ the family of its bases, $s (M; α) = \sum_{B \in B} \prod_{e \in B} α_{e}$ , where ${α_e\in \math…

Flow polynomials as Feynman amplitudes and their $α$ -representation

Eduard Yu. Lerner, Andrey P. Kuptsov, Sofya A. Mukhamedjanova

Let $G$ be a connected graph; denote by $τ (G)$ the set of its spanning trees. Let $F_{q}$ be a finite field, $s (α, G) = \sum_{T \in τ (G)} \prod_{e \in E (T)} α_{e}$ , where ${α_e\in \…
