Sydney Dynamics Group: Carlo Laing -- Dynamics and stability of chimera states in two coupled populations of oscillators

Dear all, 

This week, Friday May 22, Carlo Laing (Massey University) will give a talk at 2pm via
Zoom.  Note the unusual time.  Zoom link: https://uni-sydney.zoom.us/j/93730512710

Title: Dynamics and stability of chimera states in two coupled populations of
oscillators 

Abstract: We consider networks formed from two populations of identical oscillators,
with uniform strength all-to-all coupling within populations, and also between
populations, with a different strength.  Such systems are known to support chimera
states in which oscillators within one population are perfectly synchronised while in
the other the oscillators are incoherent, and have a different mean frequency from those
in the synchronous population.  Assuming that the oscillators in the incoherent
population always lie on a closed smooth curve C, we derive and analyse the dynamics of
the shape of C and the probability density on C, for several different types of
oscillators.  

I hope to see you all online.  Lachlan
