The fields\r\nh• : ω \u0002→ hω will act on the manifold via the conformal transformation g \u0002→ gω := e2hω g.\r\nOur focus will be on the regular case with Hurst parameter H > 0, the critical case H = 0\r\nbeing the celebrated Liouville geometry in two dimensions. We want to understand how basic\r\ngeometric and functional-analytic quantities like diameter, volume, heat kernel, Brownian\r\nmotion, spectral bound, or spectral gap change under the influence of the noise. And if so, is\r\nit possible to quantify these dependencies in terms of key parameters of the noise? Another\r\ngoal is to define and analyze in detail the Fractional Gaussian Fields on a general Riemannian\r\nmanifold, a fascinating object of independent interest."}],"publisher":"Springer Nature","oa":1,"year":"2024","month":"01","date_created":"2024-02-04T23:00:54Z","publication_status":"epub_ahead","scopus_import":"1","_id":"14934","quality_controlled":"1","date_published":"2024-01-26T00:00:00Z","status":"public","article_type":"original","department":[{"_id":"JaMa"}],"oa_version":"Published Version","doi":"10.1007/s11118-023-10118-0","project":[{"grant_number":"F6504","_id":"fc31cba2-9c52-11eb-aca3-ff467d239cd2","name":"Taming Complexity in Partial Differential Systems"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","type":"journal_article","date_updated":"2024-02-05T13:04:23Z","article_processing_charge":"Yes (via OA deal)","citation":{"ista":"Dello Schiavo L, Kopfer E, Sturm KT. 2024.
