Abstract
  • We analytically investigate the stability of {\it splay states} in networks of $N$ globally pulse-coupled phase-like models of neurons. We develop a perturbative technique which allows determining the Floquet exponents for a generic velocity field and implement the method for a given pulse shape. We find that in the case of discontinuous velocity fields, the Floquet spectrum scales as /N^2$ and the stability is determined by the sign of the jump at the discontinuity. Altoghether, the form of the spectrum depends on the pulse shape, but it is independent of the velocity field. (literal)
