We formulate and solve fixed point problems in these spaces with a class of kernels that is sufficiently large to cover in particular the Dirichlet and Neumann heat kernels. These results are then used to provide solution theories for the KPZ equation with Dirichlet and Neumann boundary conditions and for the 2D generalised parabolic Anderson model with Dirichlet boundary conditions. In the case of the KPZ equation with Neumann boundary conditions, we show that, depending on the class of mollifiers one considers, a “boundary renormalisation” takes place. In other words, there are situations in which a certain boundary condition is applied to an approximation to the KPZ equation, but the limiting process is the Hopf–Cole solution to the KPZ equation with a different boundary condition.","lang":"eng"}],"oa_version":"Published Version","scopus_import":"1","month":"04","intvolume":" 173","date_updated":"2023-08-24T14:38:32Z","ddc":["510"],"department":[{"_id":"JaMa"}],"file_date_updated":"2020-07-14T12:46:03Z","_id":"319","type":"journal_article","article_type":"original","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"status":"public","isi":1,"has_accepted_license":"1","year":"2019","day":"01","publication":"Probability Theory and Related Fields","page":"697–758","date_published":"2019-04-01T00:00:00Z","doi":"10.1007/s00440-018-0841-1","date_created":"2018-12-11T11:45:48Z","acknowledgement":"MG thanks the support of the LMS Postdoctoral Mobility Grant.\r\n\r\n","quality_controlled":"1","publisher":"Springer","oa":1,"citation":{"apa":"Gerencser, M., & Hairer, M.
