On the boundary classification of -Wright-Fisher processes with frequency-dependent selection
Clément Foucart, Xiaowen Zhou
We construct extensions of the pure-jump -Wright-Fisher processes with frequency-dependent selection (-WF processes with selection) beyond their first passage time at the bou…
Asymptotic behaviour of ancestral lineages in subcritical continuous-state branching populations
Clément Foucart, Martin Möhle
Consider the population model with infinite size associated to subcritical continuous-state branching processes (CSBP). Individuals reproduce independently according to the same su…
Limit theorems for continuous-state branching processes with immigration
Clément Foucart, Chunhua Ma, Linglong Yuan
We prove and extend some results stated by Mark Pinsky: Limit theorems for continuous state branching processes with immigration [Bull. Amer. Math. Soc. 78(1972), 242--244]. Consid…
On the explosion of the number of fragments in the simple exchangeable fragmentation-coalescence processes
Clément Foucart, Xiaowen Zhou
We consider the exchangeable fragmentation-coagulation (EFC) processes, where the coagulations are multiple and not simultaneous, as in a -coalescent, and the fragmentations dis…
On the entrance at infinity of Feller processes with no negative jumps
Clément Foucart, Pei-Sen Li, Xiaowen Zhou
Consider a non-explosive positive Feller process with no negative jumps. It is shown in this note that when infinity is an entrance boundary, in the sense that the entrance times o…
