Tropical Geometry of Biological Systems
Résumé
Tropical geometry ideas were developed by mathematicians that got inspired from very different topics in physics, discrete mathematics , optimization, algebraic geometry. In tropical geometry, tools like the logarithmic transformation coarse grain complex objects, drastically simplifying their analysis. I discuss here how similar concepts can be applied to dynamical systems used in biological modeling. In particular, tropical geometry is a natural framework for model reduction and for the study of metastability and itinerancy phenomena in complex biochemical networks.
