Our work uses Fourier analysis and leads to an analysis of exponential sums involving matrices over finite fields. These are bounded by combining a stratification result of Fouvry and Katz with a new result about the flatness of the commutator Lie bracket.","lang":"eng"}],"title":"Pairs of commuting integer matrices","date_published":"2025-10-01T00:00:00Z","date_updated":"2026-07-17T12:01:12Z","publication_identifier":{"issn":["0025-5831"],"eissn":["1432-1807"]},"doi":"10.1007/s00208-025-03285-5","oa_version":"Published Version","file_date_updated":"2026-01-05T13:15:44Z","OA_type":"hybrid","year":"2025","quality_controlled":"1","project":[{"_id":"bd8a4fdc-d553-11ed-ba76-80a0167441a3","grant_number":"P36278","name":"Rational curves via function field analytic number theory"},{"call_identifier":"H2020","grant_number":"101034413","name":"IST-BRIDGE: International postdoctoral program","_id":"fc2ed2f7-9c52-11eb-aca3-c01059dda49c"}],"author":[{"orcid":"0000-0002-8314-0177","first_name":"Timothy D","last_name":"Browning","id":"35827D50-F248-11E8-B48F-1D18A9856A87","full_name":"Browning, Timothy D"},{"last_name":"Sawin","first_name":"Will","full_name":"Sawin, Will"},{"full_name":"Wang, Victor","id":"76096395-aea4-11ed-a680-ab8ebbd3f1b9","last_name":"Wang","first_name":"Victor","orcid":"0000-0002-0704-7026"}],"isi":1,"citation":{"ista":"Browning TD, Sawin W, Wang V. 2025.
