Isotropic Matroids I: Multimatroids and Neighborhoods

[摘要] Several properties of the isotropic matroid of a looped simple graph are presented. Results include a characterization of the multimatroids that are associated with isotropic matroids and several ways in which the isotropic matroid of $G$ incorporates inf
