New approaches of source-sink metapopulations decoupling the roles of demography and dispersal
Vincent Bansaye, Amaury Lambert
Source-sink systems are metapopulations of habitat patches with different, and possibly temporally varying, habitat qualities, which are commonly used in ecology to study the fate…
Birth and death processes with neutral mutations
Nicolas Champagnat, Amaury Lambert, Mathieu Richard
In this paper, we review recent results of ours concerning branching processes with general lifetimes and neutral mutations, under the infinitely many alleles model, where mutation…
Asymptotic behavior of local times of compound Poisson processes with drift in the infinite variance case
Amaury Lambert, Florian Simatos
Consider compound Poisson processes with negative drift and no negative jumps, which converge to some spectrally positive Lévy process with non-zero Lévy measure. In this paper we…
The weak convergence of regenerative processes using some excursion path decompositions
Amaury Lambert, Florian Simatos
We consider regenerative processes with values in some Polish space. We define their ε-big excursions as excursions e such that f(e)>ε, where f is some given functional on the spac…
