Stochastic viability in an island model with partial dispersal : Approximation by a diffusion process in the limit of a large number of islands
Dhaker Kroumi, Sabin Lessard
In this paper, we study a finite population undergoing discrete, nonoverlapping generations, that is structured into demes, each containing individuals of two possible type…
Evolutionary game with stochastic payoffs in a finite island model
Dhaker Kroumi, Sabin Lessard
In this paper, we consider a two-player two-strategy game with random payoffs in a population subdivided into demes, each containing individuals at the beginning of any giv…
Noise-induced stochastic Nash equilibrium
Cong Li, Tianjiao Feng, Xiudeng Zheng +2
In order to better understand the impact of environmental stochastic fluctuations on the evolution of animal behavior, we introduce the concept of a stochastic Nash equilibrium (SN…
Average abundancy of cooperation in multi-player games with random payoffs
Dhaker Kroumi, Sabin Lessard
We consider interactions between players in groups of size with payoffs that not only depend on the strategies used in the group but also fluctuate at random over time. An…
A coalescent dual process for a Wright-Fisher diffusion with recombination and its application to haplotype partitioning
Robert C. Griffiths, Paul A. Jenkins, Sabin Lessard
Duality plays an important role in population genetics. It can relate results from forwards-in-time models of allele frequency evolution with those of backwards-in-time genealogica…
