Abstract
In this paper, we consider discrete semilinear wave equations where S is a network with boundary . The main contribution of this work is to introduce a condition for some and with , where is the first eigenvalue of discrete Laplacian , and we use the concavity method to obtain the blow-up solutions to the above equations.
