Finiteness of the graph p‑Laplacian spectrum
Determine whether the spectrum of the graph p‑Laplacian is always finite for arbitrary finite graphs and, if so, derive sharp bounds on the maximum possible number of eigenvalues (as a function of graph parameters).

Is the graph $p$-Laplacian spectrum always finite? If finite, how many eigenvalues can it have?
