Striking universalities in stochastic resetting processes

Abstract

Given a random process x(τ)x(\tau) which undergoes stochastic resetting at a constant rate rr to a position drawn from a distribution P(x){\cal P}(x), we consider a sequence of dynamical observables A1,,AnA_1, \dots, A_n associated to the intervals between resetting events. We calculate exactly the probabilities of various events related to this sequence: that the last element is larger than all previous ones, that the sequence is monotonically increasing, etc. Remarkably, we find that these probabilities are ``super-universal'', i.e., that they are independent of the particular process x(τ)x(\tau), the observables AkA_k's in question and also the resetting distribution P(x){\cal P}(x). For some of the events in question, the universality is valid provided certain mild assumptions on the process and observables hold (e.g., mirror symmetry).
