Non normal amplification of stochastic quasi-cycles
Sara Nicoletti, Niccolò Zagli, Duccio Fanelli +3
Stochastic quasi-cycles for a two species model of the excitatory-inhibitory type, arranged on a triangular loop, are studied. By increasing the strength of the inter-nodes couplin…
Hopping in the crowd to unveil network topology
Malbor Asllani, Timoteo Carletti, Francesca Di Patti +2
We introduce a nonlinear operator to model diffusion on a complex undirected network under crowded conditions. We show that the asymptotic distribution of diffusing agents is a non…
Ginzburg-Landau approximation for self-sustained oscillators weakly coupled on complex directed graphs
Francesca Di Patti, Duccio Fanelli, Filippo Miele +1
A normal form approximation for the evolution of a reaction-diffusion system hosted on a directed graph is derived, in the vicinity of a supercritical Hopf bifurcation. Weak diffus…
Benjamin-Feir instabilities on directed networks
Francesca Di Patti, Duccio Fanelli, Filippo Miele +1
The Complex Ginzburg-Landau equation is studied assuming a directed network of coupled oscillators. The asymmetry makes the spectrum of the Laplacian operator complex, and it is ul…
Drift-induced Benjamin-Feir instabilities
Francesca Di Patti, Duccio Fanelli, Timoteo Carletti
A modified version of the Ginzburg-Landau equation is introduced which accounts for asymmetric couplings between neighbors sites on a one-dimensional lattice, with periodic boundar…
Tune the topology to create or destroy patterns
Malbor Asllani, Timoteo Carletti, Duccio Fanelli
We consider the dynamics of a reaction-diffusion system on a multigraph. The species share the same set of nodes but can access different links to explore the embedding spatial sup…
