The Swiss Cheese and the Wiener Sausage – SWiWS

Submission summary

This project considers as its main object paths made by a discrete random walk, or its continuous counterpart, a Wiener Sausage. These are celebrated models of Probability Theory, and bench test models for applications in Biology, Chemistry, or Physics. We consider models of interacting random paths, either self-attracting, self-repelling or interacting with the solvent. The phenomenon we wish to describe is the folded/unfolded shape that the random path adopts according to the nature of the interaction, and the value of parameters like temperature or salt concentration. Its originality is to focus on the Newtonian Capacity of the range of the polymer, which should shed light on its geometry. The Newtonian Capacity is a central object both in Analysis and in Probability Theory. However, it has never been used to probe the geometry of models of folded polymers, as we are suggesting here.
