The damped wave equation and associated polymer

Probability 2025-09-23 v2

Abstract

Considering the damped wave equation with a Gaussian noise FF where FF is white in time and has a covariance function depending on spatial variables, we will see that this equation has a mild solution which is stationary in time tt. We define a weakly self-avoiding polymer with intrinsic length JJ associated to this SPDE. Our main result is that the polymer has an effective radius of approximately J5/3J^{5/3}.
