Spectra of Elliptic Operators on Quantum Graphs with Small Edges
We consider a general second order self-adjoint elliptic operator on an arbitrary metric graph, to which a small graph is glued. This small graph is obtained via rescaling a given fixed graph <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline&quo...
