On the critical behavior of a lattice prey-predator model
Tibor Antal, Michel Droz, Adam Lipowski +1
The critical properties of a simple prey-predator model are revisited. For some values of the control parameters, the model exhibits a line of directed percolation like transitions…
Novel criticality in a model with absorbing states
Adam Lipowski
We study a one-dimensional model which undergoes a transition between an active and an absorbing phase. Monte Carlo simulations supported by some additional arguments prompted as t…
Generic Criticality in a Model of Evolution
Adam Lipowski
Using Monte Carlo simulations, we show that for a certain model of biological evolution, which is driven by non-extremal dynamics, active and absorbing phases are separated by a cr…
Oscillatory behaviour in a lattice prey-predator system
Adam Lipowski
Using Monte Carlo simulations we study a lattice model of a prey-predator system. We show that in the three-dimensional model populations of preys and predators exhibit coherent pe…
Dimensional reduction in a model with infinitely many absorbing states
Adam Lipowski
Using Monte Carlo method we study a two-dimensional model with infinitely many absorbing states. Our estimation of the critical exponent beta=0.273(5) suggests that the model belon…
