An approach to normal forms of Kuramoto model with distributed delays and the effect of minimal delay

Abstract: Heterogeneous delays with positive lower bound (gap) are taken into consideration in Kuramoto oscillators. We first establish a perturbation technique, by which universal normal forms and detailed dynamical behavior of this model can be obtained easily. Theoretically, a hysteresis loop is found near the subcritically bifurcated coherent state on the Ott-Antonsen's manifold. For Gamma distributed delay with fixed variance and mean, we find large gap destroys the loop and significantly increases in the number of… Show more

“…In Section 4, the stability and direction of periodic solutions bifurcating from Hopf bifurcations are investigated by using the normal form theory and the center manifold theorem due to [31], which gives clearly the location where coherent states appear and their stability. In Section 5, inspired by the method given in [19,24,25], numerical simulations are carried out to support the obtained results.…”

“…Another crucial assumption is that the coupling is global (or mean field coupling). This assumption allows time-delayed or phase-shifted coupling, but excludes coupling with distributed time delays [21,28,29] or coupling through complex networks [3,34].…”
