THE DISCRETE LAPLACIAN ACTING ON 2−FORMS AND APPLICATION
Résumé
In this paper, we study the discrete Laplacian acting on 2−forms that was introduced and investigated in [7]. We establish a new criterion of essential self-adjointness using the Nelson lemma. Moreover , we give an upper bound on the infimum of the essential spectrum. Furthermore, we establish a link between the adjacency matrix and the discrete Laplacian on 2−forms.
