Query: The Kazdan-Warner equation on canonically compactifiable graphs   We study the Kazdan-Warner equation on canonically compactifiable graphs.
These graphs are distinguished as analytic properties of Laplacians on these
graphs carry a strong resemblance to Laplacians on open pre-compact manifolds.
