RT Journal Article T1 Instability and Collapse in Discrete Wave Equations A1 Carpio Rodríguez, Ana María A1 Duro, Gema AB Unstable growth phenomena in spatially discrete wave equations are studied. We characterize sets of initial states leading to instability and collapse and obtain analytical predictions for the blow-up time. The theoretical predictions are contrasted with the numerical solutions computed by a variety of schemes. The behavior of the systems in the continuum limit and the impact of discreteness and friction are discussed.
