If An is a Wigner matrix with entries in the domain of attraction of a Gaussian distribution, the empirical spectral measure of Ln is known to converge to the free convolution of a semicircle distribution and a standard real Gaussian distribution. We consider real symmetric random matrices An with independent entries (up to symmetry) whose row sums converge to a purely non-Gaussian infinitely divisible distribution, which fall into the class of Lévy–Khintchine random matrices first introduced by Jung [Trans Am Math Soc, 370, (2018)]. Our main result shows that the empirical spectral measure of Ln converges almost surely to a deterministic limit. A key step in the proof is to use the purely non-Gaussian nature of the row sums to build a random operator to which Ln converges in an appropriate sense. This operator leads to a recursive distributional equation uniquely describing the Stieltjes transform of the limiting empirical spectral measure."}],"oa":1,"volume":37,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","scopus_import":"1","date_created":"2023-08-06T22:01:13Z","ddc":["510"],"status":"public","day":"01","_id":"13975","publication":"Journal of Theoretical Probability","page":"933-973","language":[{"iso":"eng"}],"external_id":{"arxiv":["2210.07927"],"isi":["001038341000001"]},"oa_version":"Published Version","author":[{"full_name":"Campbell, Andrew J","id":"582b06a9-1f1c-11ee-b076-82ffce00dde4","first_name":"Andrew J","last_name":"Campbell"},{"last_name":"O’Rourke","first_name":"Sean","full_name":"O’Rourke, Sean"}],"file":[{"date_created":"2024-07-22T09:41:21Z","content_type":"application/pdf","file_size":555070,"file_id":"17300","file_name":"2024_JourTheorProbab_Campbell.pdf","date_updated":"2024-07-22T09:41:21Z","relation":"main_file","access_level":"open_access","checksum":"f7793d313104c70422140c5e6494c779","creator":"dernst","success":1}],"publisher":"Springer Nature","publication_status":"published","article_processing_charge":"Yes (via OA deal)","date_published":"2024-03-01T00:00:00Z","has_accepted_license":"1","month":"03","publication_identifier":{"eissn":["1572-9230"],"issn":["0894-9840"]}}
