Abstract

We propose importing results from monotone game theory to model the evolution of a bacterial population under antibiotic attack. This allows considering the bacterium aging as a relevant phenomenon moving the evolution far away from the usual linear predator-prey paradigms. We obtain an almost nonparametric aging mechanism based on a thresholding operation, as an elementary intelligent operation, that may explain some typical patterns of the population evolution. In this paper we discuss both theoretical aspects and the results of a standardized procedure.
