Subordinacy Theory on Star-Like Graphs
Netanel Levi
We study Jacobi matrices on star-like graphs, which are graphs that are given by the pasting of a finite number of half-lines to a compact graph. Specifically, we extend subordinac…

On the Decomposition of the Laplacian on Metric Graphs
Jonathan Breuer, Netanel Levi
We study the Laplacian on family preserving metric graphs. These are graphs that have a certain symmetry that, as we show, allows for a decomposition into a direct sum of one-dimen…
