Abstract:
Bounds for the multiplicity of the eigenvalues of the Sturm–Liouville problem on a graph, which are valid for a wide class of consistency (transmission) conditions at the vertices of the graph, are given. The multiplicities are estimated using the topological characteristics of the graph. In the framework of the notions that we use, the bounds turn out to be exact.
Keywords:
geometric graph, ordinary differential equation on a graph, Sturm–Liouville problem on a graph, transmission conditions, multiplicity of eigenvalues.
