One fine grading that is always present in any Lie algebra $sl(n,\\mathbb{C})$ is the Pauli grading. The MAD-group corresponding to it is generated by generalized Pauli matrices. For such MAD-group, we already know its normalizer; its quotient group is isomorphic to the Lie group $Sl(2,\\mathbb{Z}_n)\\times v\\mathbb{Z}_2$. In this paper, we deal with a more complicated situation, namely that the fine grading of $sl(p^2, \\mathbb{C})$ is given by a tensor product of the Pauli matrices of the same order $p$, $p$ being a prime. We describe the normalizer of the corresponding MAD-group and we show that its quotient group is isomorphic to $Sp(4,\\mathbb{Z}_p)\\times\\mathbb{Z}_2$.", "revisions": [ { "version": "v3", "updated": "2007-09-20T14:43:54.000Z" } ], "analyses": { "keywords": [ "generalized pauli matrices", "tensor product", "fine grading", "symmetries", "quotient group" ], "tags": [ "journal article" ], "publication": { "publisher": "AIP", "journal": "J.
