They are associated with a topological generalization of the notion of quiver, where vertices are replaced by intervals in a one-dimensional topological space. They display certain exotic features such as a Cartan subalgebra of uncountable dimension, a continuum root system with no simple roots, and they are presented by exclusively quadratic Serre relations. For these Lie algebras, we prove an analogue of the Gabber-Kac-Serre theorem, providing a complete set of defining relations.", "revisions": [ { "version": "v1", "updated": "2018-12-20T12:48:54.000Z" } ], "analyses": { "keywords": [ "topological quivers", "infinite-dimensional lie algebras", "continuum root system", "exclusively quadratic serre relations", "generalization" ], "note": { "typesetting": "TeX", "pages": 36, "language": "en", "license": "arXiv", "status": "editable" } } }
