A general multi-scale description of metastable adaptive motion across fitness valleys
Manuel Esser, Anna Kraut
We consider a stochastic individual-based model of adaptive dynamics on a finite trait graph . The evolution is driven by a linear birth rate, a density dependent logistic…

Stochastic individual-based models with power law mutation rate on a general finite trait space
Loren Coquille, Anna Kraut, Charline Smadi
We consider a stochastic individual-based model for the evolution of a haploid, asexually reproducing population. The space of possible traits is given by the vertices of a (possib…
