Characterizing spatiotemporal patterns in three-state lattice models
Matti Peltomaki, Martin Rost, Mikko Alava
A two-species spatially extended system of hosts and parasitoids is studied. There are two distinct kinds of coexistence; one with populations distributed homogeneously in space an…
Oscillations and patterns in interacting populations of two species
Matti Peltomaki, Martin Rost, Mikko Alava
Interacting populations often create complicated spatiotemporal behavior, and understanding it is a basic problem in the dynamics of spatial systems. We study the two-species case…
Three- and four-state rock-paper-scissors games with diffusion
Matti Peltomaki, Mikko Alava
Cyclic dominance of three species is a commonly occurring interaction dynamics, often denoted the rock-paper-scissors (RPS) game. Such type of interactions is known to promote spec…
Correlations in Bipartite Collaboration Networks
Matti Peltomaki, Mikko Alava
Collaboration networks are studied as an example of growing bipartite networks. These have been previously observed to have structure such as positive correlations between nearest-…
No self-similar aggregates with sedimentation
M. Peltomaki, E. K. O. Hellen, M. J. Alava
Two-dimensional cluster-cluster aggregation is studied when clusters move both diffusively and sediment with a size dependent velocity. Sedimentation breaks the rotational symmetry…
