RT Journal Article T1 Singular perturbation analysis of cAMP signalling in Dictyostelium discoideum aggregates A1 López Velázquez, Juan José A1 Liţcanu, Gabriela AB In this paper, we use singular perturbation methods to study the structure of travelling waves for some reaction-di®usion models obtained from the Martiel-Goldbeter and Goldbeter-Segel's models of cAMP signalling in Dictyostelium discoideum. As a consequence, we derive analytic formulae for quantities like wave speed, maximum concentration and other magnitudes in terms of the di®erent biochemical constants that appear in the model.
