The commutative core of a Leavitt path algebra. Gil-Canto, Cristóbal Nasr-Isfahani, Alireza Algebra Anillos (Álgebra) Política de acceso abierto tomada de: https://v2.sherpa.ac.uk/id/publication/11305 For any unital commutative ring R and for any graph E, we identify the commutative core of the Leavitt path algebra of E with coefficients in R, which is a maximal commutative subalgebra of the Leavitt path algebra. Furthermore, we are able to characterize injectivity of representations which gives a generalization of the Cuntz-Krieger uniqueness theorem. 2024-02-21T13:01:03Z 2024-02-21T13:01:03Z 2018-06-30 journal article Cristóbal Gil Canto, Alireza Nasr-Isfahani, The commutative core of a Leavitt path algebra, Journal of Algebra, Volume 511, 2018, Pages 227-248, ISSN 0021-8693, https://doi.org/10.1016/j.jalgebra.2018.06.016 https://hdl.handle.net/10630/30582 10.1016/j.jalgebra.2018.06.016 eng http://creativecommons.org/licenses/by-nc-nd/4.0/ open access Attribution-NonCommercial-NoDerivatives 4.0 Internacional Elsevier
