dynamics and then there is a dynamical noise here that is just gaussian with some covariance matrix mc that is consistently computed you know for via set of closed equations and then there is some memory kernel here mr that also needs to be consistently computed from a set of equations so i put these in very small because you know these are these are kind of hard to grasp in just like one minute but it's again some some work that comes from recent works in statistical physics and that can be directly adapted
