Sufficient and necessary conditions for the existence and smoothness of the local times, collision local times, and self-intersection local times are established for a large class of Gaussian random fields, including fractional Brownian motions, fractional Brownian sheets and solutions of stochastic heat equations driven by space-time Gaussian noise.", "revisions": [ { "version": "v1", "updated": "2015-04-18T23:20:30.000Z" } ], "analyses": { "subjects": [ "60G15", "60H05", "60H07" ], "keywords": [ "gaussian random fields", "self-intersection local times", "smoothness", "stochastic heat equations driven", "fractional brownian sheets" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2015arXiv150404776C" } } }
