We prove that the Laplace eigenvalue maximization problem of Goering et al is also dual to our embedding optimization problem. We solve the optimization problems for generalized polygons and graphs isomorphic to the one-skeltons of regular and semi-regular polyhedra.", "revisions": [ { "version": "v1", "updated": "2020-02-10T07:48:34.000Z" } ], "analyses": { "subjects": [ "05C62", "05C50" ], "keywords": [ "spectral gap", "finite graph", "optimal embedding", "laplace eigenvalue maximization problem", "optimization problem regarding embeddings" ], "note": { "typesetting": "TeX", "pages": 12, "language": "en", "license": "arXiv", "status": "editable" } } }
