This field theory treats interactions and the effect of external, possibly self-correlated noise in a perturbation about a Markovian process, thereby providing a systematic, diagrammatic approach to extreme events. We apply the formalism to Brownian Motion and calculate its survival probability distribution subject to self-correlated noise.", "revisions": [ { "version": "v1", "updated": "2021-09-08T13:51:04.000Z" } ], "analyses": { "keywords": [ "field theory", "first passage times", "non-markovian stochastic processes", "mean span", "extreme values" ], "note": { "typesetting": "TeX", "pages": 21, "language": "en", "license": "arXiv", "status": "editable" } } }
