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.","lang":"eng"}],"department":[{"_id":"JaMa"}],"language":[{"iso":"eng"}],"_id":"14934","doi":"10.1007/s11118-023-10118-0","publication":"Potential Analysis","day":"26","author":[{"first_name":"Lorenzo","last_name":"Dello Schiavo","full_name":"Dello Schiavo, Lorenzo","id":"ECEBF480-9E4F-11EA-B557-B0823DDC885E","orcid":"0000-0002-9881-6870"},{"first_name":"Eva","last_name":"Kopfer","full_name":"Kopfer, Eva"},{"first_name":"Karl Theodor","last_name":"Sturm","full_name":"Sturm, Karl Theodor"}],"type":"journal_article","publication_identifier":{"eissn":["1572-929X"],"issn":["0926-2601"]},"date_updated":"2024-02-05T13:04:23Z","month":"01","article_processing_charge":"Yes (via OA deal)","status":"public","acknowledgement":"The authors would like to thank Matthias Erbar and Ronan Herry for valuable discussions on this project.
