Stability of Spatio-Temporal Structures in a Lattice Model of   Pulse-Coupled Oscillators
  We analyze the collective behavior of a lattice model of pulse-coupled oscillators. By studying the intrinsic dynamics of each member of the population and their mutual interactions we observe the emergence of either spatio-temporal structures or synchronized regimes. We perform a linear stability analysis of these structures.
