Essential self-adjointness of the Laplacian on weighted graphs: harmonic functions, stability, characterizations and capacity [PDF]

open access: yesarXiv
We give two characterizations for the essential self-adjointness of the weighted Laplacian on birth-death chains. The first involves the edge weights and vertex measure and is classically known; however, we give another proof using stability results, limit point-limit circle theory and the connection between essential self-adjointness and harmonic ...
