It is a regularised and inertial version of the Dean–Kawasaki model. A high-probability well-posedness theory for this model is developed. This theory improves significantly on the spatial scaling restrictions imposed in an earlier work of the same authors, which applied only to significantly larger particles in one dimension. The well-posedness theory now applies in d-dimensions when the particle-width ϵ is proportional to  for  and N is the number of particles. This scaling is optimal in a certain Sobolev norm. Key tools of the analysis are fractional Sobolev spaces, sharp bounds on Bessel functions, separability of the regularisation in the d-spatial dimensions, and use of the Faà di Bruno's formula.","lang":"eng"}],"publisher":"Elsevier","file_date_updated":"2021-03-22T07:18:01Z","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","department":[{"_id":"JuFi"}],"title":"Well-posedness for a regularised inertial Dean–Kawasaki model for slender particles in several space dimensions","_id":"9240","page":"253-283","month":"05","date_updated":"2023-08-07T14:08:05Z","volume":284,"date_created":"2021-03-14T23:01:32Z","year":"2021","type":"journal_article","author":[{"id":"2CEB641C-A400-11E9-A717-D712E6697425","first_name":"Federico","full_name":"Cornalba, Federico","last_name":"Cornalba"},{"first_name":"Tony","last_name":"Shardlow","full_name":"Shardlow, Tony"},{"full_name":"Zimmer, Johannes","last_name":"Zimmer","first_name":"Johannes"}],"ddc":["510"],"article_type":"original","tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png"},"acknowledgement":"All authors thank the anonymous referee for his/her careful reading of the manuscript and valuable suggestions.
