When $\\Pi$ is not simply connected, this result extends to Laplacians acting on two-valued functions with a specified monodromy class.", "revisions": [ { "version": "v1", "updated": "2021-02-09T14:26:36.000Z" } ], "analyses": { "keywords": [ "dirichlet boundary conditions", "zeta-regularized determinant", "polygonal domains", "result extends", "finite union" ], "note": { "typesetting": "TeX", "pages": 35, "language": "en", "license": "arXiv", "status": "editable" } } }
