On the spectrum of infinite quantum graphs

Analysis and Mathematical Physics, 2022
We study the interplay between spectrum, geometry and boundary conditions for two distinguished self-adjoint realisations of the Laplacian on infinite metric graphs, the so-called Friedrichs and Neumann extensions.

The optimal general upper bound for the distinguishing index of infinite graphs

Journal of Graph Theory, 2019
The distinguishing index D′(G) of a graph G is the least cardinal number d such that G has an edge‐coloring with d colors, which is preserved only by the trivial automorphism.
