The rank of edge connection matrices and the dimension of algebras of invariant tensors
Guus Regts
We characterize the rank of edge connection matrices of partition functions of real vertex models, as the dimension of the homogeneous components of the algebra of -invariant te…

Characterizing partition functions of the vertex model
Jan Draisma, Dion Gijswijt, László Lovász +2
We characterize which graph parameters are partition functions of a vertex model over an algebraically closed field of characteristic 0 (in the sense of de la Harpe and Jones). We…
