A two-size Wright--Fisher model: asymptotic analysis via uniform renewal theory
Gerold Alsmeyer, Fernando Cordero, Hannah Dopmeyer
We consider a population with two types of individuals, distinguished by the resources required for reproduction: type- (small) individuals need a fractional resource unit of si…
Wright--Fisher kernels: from linear to non-linear dynamics, ergodicity and McKean--Vlasov scaling limits
Fernando Cordero, Christian Jorquera, Héctor Olivero +1
We study the evolution of a pathogen with two allelic types infecting a population of hosts, where within-host type frequencies evolve in discrete time. Our framework is built on a…
Two waves of adaptation: speciation induced by dormancy in a model with changing environment
Fernando Cordero, Adrián González Casanova, Jason Schweinsberg
We consider a population model in which the season alternates between winter and summer, and individuals can acquire mutations either that are advantageous in the summer and disadv…
On the block size spectrum of a class of exchangeable dynamic random graphs
Frederic Alberti, Florin Boenkost, Fernando Cordero
In this work we introduce the dynamic -random graph and the associated -coalescent with momentum. Dynamic -random graphs are a subclass of exchangeable and consistent rand…
