Abstract

Quantum graph with the Landau operator (Schrodinger operator with a magnetic field) at the edges is considered. The Kirchhoff condition is assumed at the internal vertices. We derive conditions for the graph structure ensuring the completeness of the resonance states on finite subgraphs obtained by cutting all infinite leads of the initial graph. Due to the use of a functional model, the problem reduces to factorization of the characteristic matrix-function. The result is compared with the corresponding completeness theorem for the Schrodinger quantum graph.
