Link mutations and Goeritz matrices

Lorenzo Traldi

Extending theorems of J. E. Greene [Invent. Math. 192 (2013), 717-750] and A. S. Lipson [Enseign. Math. (2) 36 (1990), 93-114], we prove that the equivalence class of a classical l…

Planarity, duality and Laplacian congruence

Derek A. Smith, Lorenzo Traldi, William Watkins

We discuss the connections tying Laplacian matrices to abstract duality and planarity of graphs.

A Characterization of Circle Graphs in Terms of Multimatroid Representations

Robert Brijder, Lorenzo Traldi

The isotropic matroid $M [I A S (G)]$ of a looped simple graph $G$ is a binary matroid equivalent to the isotropic system of $G$ . In general, $M [I A S (G)]$ is not regular, so it cannot b…

Link colorings and the Goeritz matrix

Lorenzo Traldi

We discuss the connection between colorings of a link diagram and the Goeritz matrix.
