Heuristically, this is expected to hold because Brownian motion has average spread rate O(t12) whereas the support of solutions to the deterministic PME grows only with rate O(t1m+1). The rigorous proof relies on a contraction principle up to time-dependent shift for Wong–Zakai type approximations, the transformation to a deterministic PME with two copies of a Brownian path as the lateral boundary, and techniques from the theory of viscosity solutions.","lang":"eng"}],"date_published":"2021-03-21T00:00:00Z","publication_status":"published","year":"2021","intvolume":"         9","volume":9,"ddc":["510"],"project":[{"grant_number":"665385","name":"International IST Doctoral Program","_id":"2564DBCA-B435-11E9-9278-68D0E5697425","call_identifier":"H2020"}],"isi":1,"file_date_updated":"2021-04-06T09:31:28Z","acknowledgement":"This project has received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie Grant Agreement No. 665385 .

I am also indebted to an anonymous referee for pointing out a gap in a previous version of the proof of Lemma 9 (concerning the treatment of the noise term). The issue is resolved in this version.","external_id":{"isi":["000631001700001"]},"publication_identifier":{"issn":["2194-0401"],"eissn":["2194-041X"]},"doi":"10.1007/s40072-021-00188-9","page":"892–939","author":[{"orcid":"0000-0001-7252-8072","first_name":"Sebastian","last_name":"Hensel","full_name":"Hensel, Sebastian","id":"4D23B7DA-F248-11E8-B48F-1D18A9856A87"}],"publication":"Stochastics and Partial Differential Equations: Analysis and Computations","has_accepted_license":"1","language":[{"iso":"eng"}],"_id":"9307","ec_funded":1,"citation":{"mla":"Hensel, Sebastian. “Finite Time Extinction for the 1D Stochastic Porous Medium Equation with Transport Noise.” <i>Stochastics and Partial Differential Equations: Analysis and Computations</i>, vol. 9, Springer Nature, 2021, pp. 892–939, doi:<a href=\"https://doi.org/10.1007/s40072-021-00188-9\">10.1007/s40072-021-00188-9</a>.","ieee":"S.
