As one ranges over the zeros of such quadratic forms, we use the sieve to compute the density of coprime values of polynomials, and furthermore, to address a question about local solubility in families of varieties parameterised by the zeros.","lang":"eng"}],"oa_version":"Preprint","date_published":"2021-01-01T00:00:00Z","department":[{"_id":"TiBr"}],"article_processing_charge":"No","title":"The geometric sieve for quadrics","publication_identifier":{"eissn":["1435-5337"],"issn":["0933-7741"]},"date_created":"2020-11-08T23:01:25Z","language":[{"iso":"eng"}],"project":[{"call_identifier":"FWF","_id":"26AEDAB2-B435-11E9-9278-68D0E5697425","grant_number":"P32428","name":"New frontiers of the Manin conjecture"}],"intvolume":"        33","page":"147-165","issue":"1","day":"01","volume":33,"scopus_import":"1","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2003.09593"}],"month":"01","publication":"Forum Mathematicum","citation":{"ieee":"T.
