We have decided to discontinue the publication of preprints on our preprint server end of 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV (www.arxiv.org) that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.
We use the free energy functional associated with the Fokker-Planck (forward Kolmogorov) equation to investigate the convergence to equilibrium of the Wright-Fisher model of population genetics in the case of positive mutation rates.
