We establish a sharp lower bound for the first eigenvalue and show that the equality characterizes the situation where the metric is a product. We then look at the case of a planar domain bounded by two closed curves and obtain an explicit lower bound in terms of the geometry of the domain. We finally discuss sharpness of this last estimate.", "revisions": [ { "version": "v1", "updated": "2017-09-27T13:37:06.000Z" } ], "analyses": { "subjects": [ "58J50", "35P15" ], "keywords": [ "magnetic laplacian", "first eigenvalue", "magnetic neumann boundary conditions", "explicit lower bound", "sharp lower bound" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
