【 摘 要 】
Our aim is to characterize those matrices that are the response matrix ofa semi–positive definite Schr¨odinger operator on a circular planar network.Our findings generalize the known results and allow us to consider both nonsingular and non diagonally dominant matrices as response matrices. To thisend, we define the Dirichlet–to–Robin map associated with a Schr¨odingeroperator on general networks, and we prove that it satisfies the alternatingproperty which is essential to characterize the response matrices.
