Evolving genealogies for branching populations under selection and competition
Airam Blancas, Stephan Gufler, Sandra Kliem +2
For a continuous state branching process with two types of individuals which are subject to selection and density dependent competition, we characterize the joint evolution of popu…
Right marker speeds of solutions to the KPP equation with noise
Sandra Kliem
We consider the one-dimensional KPP-equation driven by space-time white noise. We show that for all parameters above the critical value for survival, there exist stochastic wavelik…
Evolving phylogenies of trait-dependent branching with mutation and competition. Part I: Existence
Sandra Kliem, Anita Winter
We propose a type-dependent branching model with mutation and competition for modeling phylogenies of a virus population. The competition kernel depends for any two virus particles…
Travelling wave solutions to the KPP equation with branching noise arising from initial conditions with compact support
Sandra Kliem
We consider the one-dimensional KPP-equation driven by space-time white noise and extend the construction of travelling wave solutions arising from Heavyside initial data from [Tri…
Existence of mark functions in marked metric measure spaces
Sandra Kliem, Wolfgang Löhr
We give criteria on the existence of a so-called mark function in the context of marked metric measure spaces (mmm-spaces). If an mmm-space admits a mark function, we call it funct…
A compact containment result for nonlinear historical superprocess approximations for population models with trait-dependence
Sandra Kliem
We consider an approximating sequence of interacting population models with branching, mutation and competition. Each individual is characterized by its trait and the traits of its…
