Abstract

A network encodes a structure of individual units (the nodes), together with the information of how these units depend on each other. We project focus on qualitative changes in the dynamics of networks as one or more parameters vary. One can, for example, think about the emergence of steady state points or periodic orbits, or the phenomenon where by multiple cells in a network start displaying identical dynamical behaviour (synchronisation). Due to the nature of network structures, the symmetries are often more "exotic" than compact groups; equivariance of a dynamical system will often mean with respect to the action of a finite monoid (i.e. a group without inverses) and there presentations in question will often be of semigroups. The project deals with such normal form reduction to understand how collective dynamics appear with such systems. (AU)
