An orthogonality relation for characters of finite abelian groups (now recognized as an orthogonality relation on $\\mathrm{GL}(1)$) was used by Dirichlet to prove infinitely many primes in arithmetic progressions. Orthogonality relations for $\\mathrm{GL}(2)$ and $\\mathrm{GL}(3)$ have been worked on by many researchers with a broad range of applications to number theory. We present here, for the first time, very explicit orthogonality relations for the real group $\\mathrm{GL}(4,\\mathbb{R})$ with a power savings error term. The proof requires novel techniques in the computation of the geometric side of the Kuznetsov trace formula.", "revisions": [ { "version": "v1", "updated": "2019-10-30T00:02:50.000Z" } ], "analyses": { "subjects": [ "11F55", "11F72" ], "keywords": [ "power savings error term", "kuznetsov trace formula", "finite abelian groups", "explicit orthogonality relations", "geometric side" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
