Matthew Parker, Alex Kamenev, Baruch Meerson
We investigate a model where strong noise in a sub-population creates a metastable state in an otherwise unstable two-population system. The induced metastable state is vortex-like…

Extinction in Lotka-Volterra model
Matthew Parker, Alex Kamenev
Competitive birth-death processes often exhibit an oscillatory behavior. We investigate a particular case where the oscillation cycles are marginally stable on the mean-field level…
