Rescaling limits of the spatial Lambda-Fleming-Viot process with selection
Alison Etheridge, Amandine Veber, Feng Yu
We consider the spatial Lambda-Fleming-Viot process model for frequencies of genetic types in a population living in R^d, with two types of individuals (0 and 1) and natural select…
Conditioning the logistic branching process on non-extinction
Alison Etheridge, Shidong Wang, Feng Yu
We consider a birth and death process in which death is due to both `natural death' and to competition between individuals, modelled as a quadratic function of population size. The…
Fixation Probability for Competing Selective Sweeps
Feng Yu, Alison Etheridge, Charles Cuthbertson
We consider a biological population in which a beneficial mutation is undergoing a selective sweep when a second beneficial mutation arises at a linked locus and we investigate the…
Stationary distribution for dioecious branching particle systems with rapid stirring
Feng Yu
We study dioecious (i.e., two-sex) branching particle system models, where there are two types of particles, modeling the male and female populations, and where birth of new partic…
Asymptotic behavior of the rate of adaptation
Feng Yu, Alison Etheridge, Charles Cuthbertson
We consider the accumulation of beneficial and deleterious mutations in large asexual populations. The rate of adaptation is affected by the total mutation rate, proportion of bene…
Stationary distributions of a model of sympatric speciation
Feng Yu
This paper deals with a model of sympatric speciation, that is, speciation in the absence of geographical separation, originally proposed by U. Dieckmann and M. Doebeli in 1999. We…
Equilibrium States of Two Stochastic Models in Mathematical Ecology
Feng Yu
This work deals with two problems arising in mathematical ecology. The first problem is concerned with diploid branching particle models and its behavior when rapid stirring is add…
